Price of stainPhysical properties the total heat transfer coefficient of metal depends not only on the thermal conductivity of metal, rust scale and the surface condition of metal. Stainless steel can keep the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory stainless steel provides the technical standard of stainless steel plate Stainless steel plate high-strength stainless steel plate with excellent corrosion resistance, bending workability, toughness of welding parts and stamping workability of welding parts. Specifically, Si, Mn, P, s, Al and Ni with an appropriate content of less than 0.02% of C, more than 11% of Cr and less than 17% shall meet 12 & le; Cr Mo 5Si & le; 11 & le; Ni 30 (c n) 0.5 (Mn Cu) & le; Cr 0.5 (Ni Cu) 3Mo & Ge; 0, 0.006 & le; C, n & le; 0.030 stainless steel plate is heated to 850 ~ 1250 ℃, and then cooled at a cooling rate of more than 1 ℃ / S. in this way, it can become a high-strength stainless steel plate with martensite content of more than 12%, high strength of more than 730mpa, corrosion resistance and bending processability, and excellent toughness of welding heat affected zone. It can be significantly improved by reusing Mo, B etc High stamping performance of welded parts.
Steel strip material: different steel strip materials determine the quality of stainless steel, which is a major factor affecting the price of stainless steel at present.
.When improved, it is possible to use it in refrigeration related engineering. Recently, sus430lx (18cr Ti, Nb LC) and sus436l have been applied to frozen shells. Ferritic stainless steel has body centered cubic structure. When the material properties become weaker, sharp cracks will expand rapidly and cause brittleness. Austenitic series stainless steel will not produce brittleness because it has face centered cubic structure. Austrian stainless steel SUSL (18cr-9ni LC) and SUSL (18cr-12ni-2mo-lc) shows that it still has superior impact characteristics at low temperature. However, pay attention to the precipitation of ferrite or martensite due to processing, and the tendency of embrittlement due to sensitized carbide or & sigma; equal heterogeneous precipitation.
High pressure water jet cutting (professional water cutting: Shanghai Xinwei)
.It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content, its wear-resistant corrosion and fatigue corrosion properties are better than austenitic stainless steel.
Delivery status: to be delivered after heat treatment and leveling.
From the perspective of metallography, because stainless steel contains chromium, a very thin chromium film is formed on the surface, which is separated from the corrosion resistance of oxygen invaded in the steel.
4: stainless steel strip (stainless steel coil): or coil,Stainless steel pipe support, coil, coil,321 stainless steel belt manufacturer, plate coil. There are many names, and the hardness of the strip varies from dozens to hundreds. The customer needs to determine which hardness to use first. (8K mirror luminosity)
Welding, high frequency preheating plus three torch argon arc welding, high frequency preheating plus plasma argon arc welding. The progress of combined welding is very significant. As for the combined welding of steel pipe with high-frequency preheating, the weld quality is equivalent to the conventional argon arc welding and plasma welding, the welding operation is complex, and the whole welding is easy to complete automation. This combination is easy to connect with the existing high-frequency welding equipment, with low investment cost and good benefit.
L stainless steel pipe is a kind of hollow long round steel, which is mainly used for industrial transmission pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment food, light industry, machinery and instruments, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in all kinds of manufacturing mechanical parts and engineering structures.
target.The steel grades for JIS mechanical structures are: S + carbon content + letter code (CK), in which the carbon content is represented by the intermediate value & times; 100, the letter C: represents carbon, and K: represents steel for carburizing. For example the carbon content of carbon coil s20c is 0.18-0.23%. The grades of silicon steel sheets in China and Japan are.
2: stainless steel pipe: seamless pipe and seamless pipe (longitudinal welded pipe, decorative pipe, welded pipe, welded pipe, bright pipe). There are more than 200 kinds of standard specifications of stainless steel pipe,904L plate stainless steel, all sizes, and the small pipe is more expensive, especially the capillary. The capillary is poor to be made of 304 material, otherwise the pipe is easy to burst. You can also customize non-standard pipes for customers. Seamless pipes are mainly used in industry, and the surface is foggy, Not bright. The surface of the slotted pipe is a bright surface, and there is a thin welding line in the pipe, commonly known as welded pipe, which is mainly used for decorative materials. In addition the pressure resistance of industrial fluid pipe depends on the wall thickness. 310 and 310S are high temperature resistant pipes. They can be used normally below 1080 degrees, and the high temperature resistance can reach 1150 degrees
Logistics cost: different delivery locations determine different transportation costs. The long-distance transportation cost should be 500 yuan per ton and the short-distance transportation cost should be about 300 yuan per ton.
1: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface, including 2B plate and Ba plate. In addition, it can also be plated with other light colors according to customer requirements. The main specifications of plates are: 1m * 1m, 22m * 44m 5m * 3M, 5m * 6m. If customer demand is large, we can cut them according to customer size. In addition, we can replace wire drawing plate, anti sliding plate and electroplating plate
Good quality.In addition to stress corrosion resistance, professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe have stable, safe and reliable performance and can be maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. Other local corrosion resistance properties are better than ferritic stainless steel.
AUSTENITIC FERRITIC duplex stainless steel on the basis of austenitic stainless steel, appropriately increase Cr content and reduce Ni content, and cooperate with remelting treatment. High prices, various specifications of stainless steel plates, stainless steel coils, stainless steel belts and stainless steel tubes are supplied in time and cost-effective. It has become the preferred brand for many wire products. Welcome to buy! Stainless steel with duplex structure of austenite and ferrite (including 40 ~ 60% & Delta; - ferrite) can be obtained. Typical steel grades include 0cr21ni5ti 1Cr21Ni5Ti, ocr21ni6mo2ti, etc. Duplex stainless steel has good weldability, no heat treatment is required after welding, and its tendency of intergranular corrosion and stress corrosion is also small. However, due to the high Cr content, it is easy to form & sigma; Pay attention when using.
SPHC—& mdash; In the first place, s is the abbreviation of steel, P is the abbreviation of plate, h is the abbreviation of hot heat, and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.
.Cold formed alloys can be cut and cold formed. However, due to its high strength and hardness, the alloy needs cold forming more than austenitic steel. Because of its high strength, it is not easy to polish (BQ is not good). If the hardness is too low, orange peel is easy to appear on the surface during deep drawing, which affects BQ performance. BQ with high hardness is relatively good.
As we all know, stainless steel pipe has a strong ability of atmospheric oxidation and is not easy to rust under normal circumstances, & ldquo; Stainless steel pipe & rdquo; Hence the name of. But what I want to tell you today is that stainless steel pipes will also rust. I believe many friends will be surprised! I believe there are many people who don't know how to explain to customers! Next, let's popularize science!
