18Cr-8Ni
As a wide range of uses of steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; stamping, bending and other hot workability is good, no heat treatment hardening phenomenon (non-magnetic, will be used in the temperature of the C. C. - 196 ℃ ~ 800 ℃).
Household goods (1, 2 types of tableware, cabinets, indoor plumbing, water heaters, boilers, bathtubs), automotive parts (windshield wipers, mufflers, molded products), medical equipment, building materials, chemical, food industry, agriculture, ship parts.
304L
18Cr-8Ni-low carbon as a low-C 304 steel, in the general state, its corrosion resistance is similar to 304 just, but after welding or stress relieving, its resistance to grain boundary corrosion is excellent; in the absence of heat treatment, it also maintains good corrosion resistance, the use of the temperature -196 ℃ ~ 800 ℃. Used in chemical, coal, petroleum industry with high resistance to grain boundary corrosion requirements of the field open-air machinery, building materials, heat-resistant parts and heat treatment of parts with difficulties.
316
18Cr-12Ni-2.5Mo due to the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used in harsh conditions; work hardening of excellent (non-magnetic) seawater in the equipment, chemicals, dyes, papermaking, oxalic acid, fertilizers, and other production equipment; photographic, food industry, coastal facilities, ropes, CD rods, Bolts, nuts. 316L
18Cr-12Ni-2.5Mo low carbon
As a 316 steel grade of low C series, in addition to the same characteristics as 316 steel, its resistance to grain boundary corrosion is superior.
The use of 316 steel has a special requirement for products with resistance to grain boundary corrosion.
