What is the difference between stainless steel raw materials 301 and 304?

What is the difference between stainless steel raw materials 301 and 304? 301 is 4% nickel content, 304 nickel content 8. It is not wiped in the same outdoor atmosphere, it will not rust in 304, 3-4 years, and 301 will start to rust in 6 months. It will be difficult to see in 2 years. Stainless... Read More

Difference between 304 and 321 stainless steel

Difference between 304 and 321 stainless steel The main difference between 304 and 321 stainless steel is that 304 does not contain Ti, and 321 contains Ti. Ti can avoid stainless steel sensitization. In short, it is to improve the service life of stainless steel in high temperature practice. Th... Read More

raw materials for stainless steel pipes

There are several raw materials for stainless steel pipes 2019-09-30 Stainless steel pipe varieties are divided into: 1 stainless steel seamless steel pipe; 2 stainless steel welded pipe. According to brightness: general stainless steel tube, matte stainless steel tube, bright stainless steel ... Read More

300 series-ferritic and martensitic stainless steel

Type 301-Good ductility, used for molded products. It can also be quickly hardened by machining. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel. Type 302-anti-corrosion can be the same as 304, because the carbon content is relatively high, so the s... Read More

400 Series-Ferritic and Martensitic Stainless Steel

400 Series-Ferritic and Martensitic Stainless Steel Type 408-Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni. Type 409-the cheapest type (British-American), generally used as car exhaust pipe, is a ferritic stainless steel (chrome steel). Type 410-Martensite (high-strength chrom... Read More

What is stainless steel 201 ?

201 stainless steel is a 200 series austenitic stainless steel developed by replacing manganese, nitrogen and other elements with nickel. It has good corrosion resistance and hot and cold processing functions, which is sufficient to replace the indoor, inland cities and outdoor use. 304 stainless... Read More

Stainless Steel Divided by Raw Materials

Stainless steel raw materials are generally divided into: 1. Ferritic stainless steel. Contains 12% to 30% of chromium. Its corrosion resistance, resistance and weldability improve with the addition of chromium content, and the resistance to chloride stress corrosion is better than other ... Read More

Steel Classification by Shape

 It can be divided into four categories:a. Profile, b. Sheet, c. Pipe, and d. Metal products. a. Profile: Heavy rail, steel rails (including crane rails) with a weight of more than 30 kg per meter; light rails, steel rails with a weight of 30 kg or less per meter. Large section steel: general ... Read More

What steel is high temperature resistant?

 What steel is high temperature resistant? There are many types of steel, but their functions are not exactly the same. Generally, we refer to high-temperature steel as “heat-resistant steel”. Heat-resistant steel refers to a class of steels that have oxidation resistance and satisf... Read More

What is Cold Rolled Sheet?

 A cold-rolled sheet is a sheet made by rolling a hot-rolled coil as a material and rolling below the recrystallization temperature at room temperature. In the entire process of cold-rolled sheet production, because no heating is performed, there are no defects such as pits and scales often prese... Read More

What is Hot Rolled Coil ?

Hot rolled coils use slabs (mainly continuous cast slabs) as materials, and after heating, strips are assembled by rough rolling units and finishing rolling units. Hot-rolled coils are cooled by laminar flow to the set temperature from the final rolling mill. The coils are rolled into coils. Afte... Read More

What is Special Steel?

 The definition of special steel is not clearly defined internationally, and the calculation classification of special steel in different countries is not the same. The special steel industry in China covers Japan and Europe. It includes three types of high-quality carbon steel, alloy steel, an... Read More
