Stainless stee
304ti stainlesCutting tool level & rdquo; Martensitic steel, an early stainless steel similar to Brinell high chromium steel. It is also used for surgical tools, which can be made very bright.
The specification and appearance quality shall comply with the provisions of gb14975-2002 stainless steel seamless steel pipe. The steel pipe is usually 5 ~ 10m long (indefinite length) hot rolled steel pipe, and the hot-rolled steel pipe is equal to or greater than 1m. The wall thickness of cold drawn (rolled) steel pipe is 0.5 ~ 0mm, 0 ~ 7m; the wall thickness is greater than 0mm, 5 ~ 8m.
.Using CrO3 and h2so4h2o as the main components and adding an appropriate amount of mnso4.4h2o coloring solution, the chemical coloring of stainless steel industrial pipe was carried out. The effects of pretreatment process, coloring solution temperature, mass concentration and coloring time on the color film of stainless steel industrial pipe were discussed. Through a large number of experiments, a good formula and process range of coloring solution are obtained. With the increase of temperature and time, the film thickness increases, and the color changes are brown, blue, purplish red and green. After curing and sealing treatment, the colored film of stainless steel industrial pipe has more uniform surface color good reproducibility, and significantly improved wear resistance and corrosion resistance.
·Rotary shaft, press roller, blade impeller, etc. in high-strength corrosion-resistant environment.
.Allowable depth of straight track: hot rolled and hot-rolled steel pipes with diameter less than or equal to 140mm shall not be greater than 5% of the nominal wall thickness, and the large depth shall not be greater than 0.5mm; cold drawn (rolled) steel pipes shall not be greater than 4% of the nominal wall thickness, and the large depth shall not be greater than 0.3mm.
The large electric clamping tool is 220V power supply, and the motor drives the oil cylinder to clamp. The connecting oil pipe and quick connector must not be contaminated,100mm stainless steel square pipe, otherwise the dirt entering the oil circuit system will affect the normal use of the tool. Connect the main engine and hydraulic cylinder, turn on the power supply first, then tighten the pressure relief valve, or the main engine automatically trips then open the pressure relief valve, turn off the power supply, and remove the tong head after complete pressure relief.
Spcespce & mdash; & mdash; refers to cold-rolled carbon steel sheet and strip for deep drawing, equivalent to China 08Al (52) deep drawing steel. If it is necessary to ensure non aging property, add n at the end of the brand as spcen. Quenching and tempering code of cold-rolled carbon steel sheet and strip: annealing status is a, standard quenching and tempering is s,Stainless steel plate coloring, 1 / 8 hard is 1 / 4, hard is 1 / 2, hard is 1. Surface processing code: dull finish rolling is D, bright finish rolling is B. spcc-sd represents cold-rolled carbon sheet generally used for standard quenching and tempering and matt finish rolling. Another example is spcct-sb It refers to cold-rolled carbon sheet with standard quenching and tempering and bright processing and required to ensure mechanical properties.
For the length of welding arc, 2 ~ 4mm is better for ordinary steel welding, and ~ 3mm is better for stainless steel welding. If it is too long, the protection effect is not good.
When installing and welding the fixed port of stainless steel pipe it is difficult to vent on the inner side, and some sides are easy to be blocked. In this case, water-soluble paper + blocking plate can be used for blocking. That is, the easy to vent and good side can be blocked with blocking plate, the difficult to vent and bad blocking plate side can be blocked with water-soluble paper, and the weld on the outer side can be blocked with adhesive tape (see Table 2) .
The large electric clamping tool is 220V power supply, and the motor drives the oil cylinder to clamp. The connecting oil pipe and quick connector must not be contaminated, otherwise the dirt entering the oil circuit system will affect the normal use of the tool. Connect the main engine and hydraulic cylinder, turn on the power supply first, then tighten the pressure relief valve, wait until the pressure gauge rises to about 45MPa, or the main engine automatically trips, then open the pressure relief valve, turn off the power supply, and remove the tong head after complete pressure relief.
Workshop cost.However, some people will still communicate online or by telephone to ask whether the stainless steel pipe we produce can be used as a water pipe.

Stainless steel is a common steel in stainless steel, also known as 188 stainless steel. It is characterized by high temperature resistance, so it is made into a frequently used steel. Common in life are stainless steel pipe, stainless steel plate, stainless steel coil and other building materials. As a very important building material, construction industry, home decoration industry and food and medical industry. It is one of the indispensable materials in life! So what items are made of stainless steel in our life? Let's have a look!
Process performance inspection: flattening test, tensile test, impact test, flaring test, hardness test, metallographic test, bending test and nondestructive testing (including eddy current testing, X-ray testing and ultrasonic testing).
Honesty and mutual benefit. 630— Common precipitation hardening stainless steel models, products and tens of millions of products are up to you to choose. Professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe are safe and secure. They are usually also called 17-17% Cr and 4% Ni.
Model 440 & mdash; High strength cutting tool steel, with slightly higher carbon content, and the hardness can reach 58hrc. It belongs to hard stainless steel. A common application example is & ldquo; Shaving blade & rdquo;. There are three common models: 440C and 440f (easy to process).
Cold rolled stainless steel strip; Stainless steel strip / coil & rdquo; As raw material, it is rolled by cold rolling mill at room temperature. General thickness & amp; lt; 0.1mm～3mm& gt;, Width & amp; lt; 100mm～2000mm& gt;； [& ldquo; cold rolled steel strip / coil & rdquo;] has the advantages of smooth and smooth surface, high dimensional accuracy and good mechanical properties. Most products are rolled and can be processed into coated steel plate; Production process of cold rolled stainless steel strip / coil: 1. Pickling → 2. Normal temperature rolling → 3. Process → 4. Annealing → 5. Leveling → ⒍ fine cutting → ⒎ packaging → 8. Reach customers.
.Cold rolled oriented silicon steel strip consists of nominal thickness (expanded by 100 times) + code G: ordinary material, P: high oriented material + guaranteed iron loss value (the value after expanding the iron loss value when the frequency is 50Hz and the large magnetic flux density is 7T by 100 times). For example, 30g130 indicates that the thickness is 0.3mm and the guaranteed value of iron loss is ≤ 3 cold rolled oriented silicon steel strip. Liaocheng Suntory stainless steel provides electroplated tin plate and hot-dip galvanized plate: electroplated tin plate, electroplated tin sheet and steel strip, also known as tinplate. The surface of the steel plate (belt) is plated with tin, which has good corrosion resistance. In addition it can be used as packaging material for cans, inner and outer sheath of cables, instrument and telecommunication parts, flashlight and other hardware.
Low temperature embrittlement --- in low temperature environment, the deformation energy is small. In the low temperature environment, the phenomenon that the elongation and area shrinkage decrease is called low temperature embrittlement. Most of them are produced on the body centered cubic structure of ferrite series.
Stainless steel pipes are not easy to rust as long as they are not in particularly polluted places. 201 stainless steel is easy to rust. These two can be tested with magnet. They are not magnetic and can not be absorbed by magnet.
