The surface of the steel strip in the state of supply shall be rough or bright.

500 Series & mdash; Heat resistant chromium alloy steel.

.Ferritic stainless steel the Cr content of ferritic stainless steel is generally 13% ~ 30% and the carbon content is less than 0.25%. Other alloying elements are sometimes added. The metallographic structure is mainly ferrite, it also has good hot workability and certain cold workability. Ferritic stainless steel is mainly used to make components with high corrosion resistance and low strength requirements. It is widely used in manufacturing equipment such as production and there is no & alpha during heating and cooling=& amp; amp;gt;& gamma; The transformation cannot be strengthened by heat treatment. Strong oxidation resistance. At the same time, nitrogen fertilizer and chemical pipelines.

Today, Xiaobian can help you. If you want to choose high-quality stainless steel pipe water supply pipe you can choose this: choose the material of stainless steel pipe water supply pipe.

.Basic weight (density) / kg of steel plate: SPCC & mdash& mdash; Cold rolled carbon steel sheet and strip are generally used, which is equivalent to q195a. The third letter C is the abbreviation of cold. When it is necessary to ensure the tensile test, add t at the end of the brand as spcct.

With the development of social economy, the application of stainless steel pipe has been more and more popular. It will bring new changes in various fields.

The surface quality appearance and dimensional accuracy of cold rolled steel strip are better than those of hot rolled plate.

From the perspective of metallography, because stainless steel contains chromium, which is separated from the corrosion resistance of oxygen invaded in the steel.

The bright nickel layer on the stainless steel pipe is a silver white metal with slight yellow light. Its hardness is higher than that of copper, zinc, tin, cadmium, gold and silver, but lower than that of chromium and rhodium. Bright nickel has high chemical stability in air and good stability to alkali. Using Brightener on stainless steel pipe, bright nickel can be directly plated without polishing, so as to improve the hardness, wear resistance and leveling of the surface, make the appearance of stainless steel pipe consistent with other nickel plated parts, and avoid the corrosion of potential difference between stainless steel pipe and other bright nickel. After using bright nickel solution for a period of time, due to the of brightener

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,Stainless steel compression fittings,Stainless steel pipe making machine, 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.

Good reputation.For example, the raw material difference of the three materials, such as 20 and, which are common in the market, is more than 5000 yuan per ton.

  SPHESPHE—& mdash; Hot rolled steel plate and strip for deep drawing.

The method is that the heated tube blank is placed in a closed cylinder, and the perforated rod and rod move to extrude the part from the smaller die hole. This method can produce steel pipes with smaller diameter.

Hot rolled belt, stainless steel etching belt, stainless steel stretching belt, stainless steel polishing belt, stainless steel soft belt, stainless steel hard belt, stainless steel medium hard belt, stainless steel high temperature resistant belt, etc.

Variable cost.Steel strip material: different steel strip materials determine the quality of stainless steel, so that the corrosion resistance of the steel will be greatly improved. As mentioned above, in order to prevent intergranular corrosion, solid solution treatment is usually used to dissolve Cr23C6 in austenite and then cool rapidly. Air cooling can be adopted for parts, and water cooling is generally adopted.

Organic substances (such as melons and vegetables, noodle soup, phlegm, etc.) adhered to the surface of stainless steel constitute organic acids in the presence of water and oxygen. For a long time, the corrosion of organic acids on the metal surface.

.The requirements for weldability and weldability vary from product to product. A tableware usually does not need welding performance, and even includes some pot enterprises. However, most products require good welding performance of raw materials,2-inch stainless steel pipe, such as class II tableware, thermos cup, steel pipe, water heater, water dispenser, etc.

Compared with traditional steel, stainless steel can not only ensure high strength and weight ratio, but also have good plasticity, formability and weldability. It is the first choice for car frame. Stainless steel with superior performance can create cars with light weight, strong resistance, high safety and long service life. Such frames can be recycled and reused. It can not only save costs, but also save resources. And some other auto parts are also made of stainless steel. Stainless steel has a great potential market in the whole automobile industry!

When brown rust spots appear on the surface of stainless steel pipes, people will be surprised: & ldquo; Stainless steel pipes are not rusty. Is there a problem with the steel quality;. In fact
