Section Steel According to material

Stainless steel round steel materials are: 304,304 L, 321,316,316 L, 310S, 630,1Cr13, 2Cr13, 3Cr13,1Cr17Ni2, dual phase steel, antibacterial steel and other materials, mainly used in: petroleum, electronics, chemicals, medicine, Spinning, food, machinery, construction, nuclear power, aerospace, military and other industries, but according to the different materials, its application is also slightly different.

200 series - chrome - nickel - manganese austenitic stainless steel

300 series - chrome - nickel austenitic stainless steel

301 - good ductility, for molding products. Can also be hardened by speed. Good weldability. Abrasion resistance and fatigue strength better than 304 stainless steel.

302 - corrosion resistance with the 304, due to the relatively high carbon content and thus better strength.

303- by adding a small amount of sulfur, phosphorus to make it more cutting.

304- 18/8 stainless steel. GB grade 0Cr18Ni9.

309 - has a better temperature resistance than 304.

316 - Following the 304, the second most widely used steel, mainly for the food industry and surgical equipment, add molybdenum elements to obtain a special anti-corrosion structure. Because it is better than the 304 resistance to chloride corrosion and therefore also for the "marine steel" to use. SS316 is usually used for nuclear fuel recovery devices. 18/10 grade stainless steel is also usually in line with this application level.

321 - In addition to the addition of titanium to reduce the risk of corrosion of the material welds other than the performance of similar 304.

400 series - ferrite and martensitic stainless steel

408 - good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.

409 - the cheapest model (Anglo-American), usually used as a car exhaust pipe, is a ferritic stainless steel (chrome steel).

410 - martensite (high strength chrome steel), good wear resistance, poor corrosion resistance.

416 - Added sulfur improves the processability of the material.

420 - "cutting edge" martensitic steel, similar to Brinell high chrome steel this first stainless steel. Also used for surgical instruments, can be done very bright.

430-ferrite stainless steel, decorative, for example for car accessories. Good formability, but poor in temperature and corrosion resistance.

440 - high strength cutting tool steel, slightly higher carbon, after a proper heat treatment can get a higher yield strength, hardness can reach 58HRC, are the hardest stainless steel column. The most common application example is the "shaving blade". There are three commonly used models: 440A, 440B, 440C, in addition to 440F (easy to type). Cold drawn steel is cold drawn from the processing of a variety of cross-sectional shape and size of the steel, cold drawn steel, also known as cold drawn steel, cold drawn steel. Cold drawn steel can be divided into cold drawn steel, cold drawn steel, cold drawn flat steel, cold drawn hexagonal steel, cold drawn shaped steel. Cold-drawn steel can be used for machine tool manufacturing, hydropower equipment manufacturing, woodworking machinery manufacturing, automobile and motorcycle bicycle accessories, standard parts, agricultural machinery, machinery and equipment manufacturing, textile machinery processing factory for supporting, has been widely used in machine tool manufacturing, Machinery and equipment, construction machinery, construction machinery, elevators, fitness equipment, aerospace and other industries. Diesel, musical instruments, household appliances, office equipment, steel furniture and handicrafts, decorations, lighting industry, hardware decoration industry, instrumentation,
