Stainless steel can be classified according to composition Cr system (SUS400), Cr-Ni system (SUS300), Cr-Mn-Ni (SUS200) and the Department of precipitation hardening (SUS600).
200 Series - chromium - nickel - manganese austenitic stainless steel
300 Series - chromium - nickel austenitic stainless steel
301 - ductile, for formed products. Machine speed can also be hardened. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel.
302 - 304 with corrosion resistance, due to relatively high carbon intensity and therefore better.
303 - by adding a small amount of sulfur, phosphorus, making them less cut processing.
304 - or 18 / 8 stainless steel. GB grades for 0Cr18Ni9.
309 - compared to 304 a better temperature resistance.
316 - Following the 304, the second most widely used of steel, mainly used in food industry and surgical equipment, add molybdenum to obtain a special corrosion-resistant structure. Better than the 304 because of its resistance to chloride corrosion and thus as "marine steel" to use. SS316 is often used to fuel recovery. 18/10 grade stainless steel is usually in line with the application level. [1]
Model 321 - not only because titanium elements added to reduce the risk of corrosion of the weld material properties similar to other than 304.
400 Series - ferritic and martensitic stainless steel
408 - heat resistance, corrosion resistance is weak, 11% Cr, 8% of Ni.
409 - the cheapest model (Anglo-American), often used as a car exhaust pipe, is a ferritic stainless steel (chrome steel).
410 - martensite (high-strength chromium steel), wear resistance, corrosion resistance is poor.
416 - added sulfur improves the processing performance of materials.
420 - "cutting class" martensitic steel, high chrome steel, this Brinell similar to the first stainless steel. Also used in surgical tools, can be made very light.
430 - ferritic stainless steel, decorative, such as for automotive accessories. Good formability, but the temperature resistance and corrosion resistance worse.
440 - high-strength steel cutting tools, carbon slightly higher, after appropriate heat treatment to obtain a higher yield strength, hardness can achieve 58HRC-62HRC, are among the most hard stainless steel as well. The most common application example is the "bearing." There are three commonly used models: 440A, 440B, 440C, in addition to 440F (and easy processing).
500 series - heat-resistant chromium alloy steel.
600 Series - martensitic precipitation hardening stainless steel.
630 - The most common type of precipitation hardening stainless steel, commonly known as 17-4; 17% Cr, 4% Ni.
Shielded bearings
Shielded bearings, suffix 2Z, dust cover is made of stainless steel. Shield Jade inner shoulder to form a very narrow gap, and can withstand high temperatures and high speed. Shielded bearings are mainly used in the inner ring rotating conditions. If the outer ring rotation, the bearing at high speed, will lead to grease leakage.
Bearings with seals
Bearings with contact seals, suffix 2RS1, ring by a steel skeleton of the oil and abrasion resistant nitrile rubber fixed. This allows the seals Xie operating temperature -40 to +100 ��, in a short time up to +120 ��. Sealing lip contact seal with the inner shoulder seal. The outer edge of the groove in the outer ring in this location can provide a good seal.
When the sealed bearings running under certain extreme conditions, such as high speed or high temperature, may lead to grease leakage between the inner ring and ring. If the leak will damage the bearing arrangement of the impact, it certainly need to go through a special design steps.
