I: stainless steel, brand 3 16.
Two: chemical composition
C:≤0.08？ Si≤ 1.00？ Mn≤2.00？ P≤0.035？ S≤0.030？ ni 1 1.00 ~ 14.00？ Cr 16.00~ 19.00
Mo 1.80~2.50？ Ti≥5*C%~0.70
Features: due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and it can be used under harsh conditions; Excellent work hardening (nonmagnetic); Excellent high temperature strength; The solid solution state is nonmagnetic; Cold-rolled products have good luster and beautiful appearance; Compared with 304 stainless steel, the price is higher.
The corrosion resistance and high temperature strength of 3 16 stainless steel are greatly improved by adding Mo element, and the high temperature resistance can reach 1200- 1300 degrees, which can be used under harsh and cool conditions.
Uses: The equipment is used for seawater, chemical industry, dyestuff, papermaking, oxalic acid, fertilizer and other production equipment; Photography, food industry, facilities in coastal areas, ropes, CD rods, bolts and nuts.
Foshan Zheng Gang 3 16 sanitary grade stainless steel
What do you mean by hygiene grade?
Sanitary grade stainless steel pipe 3A certification:
In the field of food and drug production and equipment manufacturing, "3-A" standard is recognized as an important international health standard.
Sanitary stainless steel tube 3A contains a series of dairy products and food production equipment, such as pumps, valves, sanitary fittings, hose assemblies, flowmeters, filters, sensors, storage tanks, food packaging equipment, rubber and plastic parts materials, etc.
Each product standard involves all aspects of stainless steel equipment, which is detailed and specific. Include structural materials (metal, solder, rubber, plastic, adhesive or lubricant, etc.). ), surface roughness, welding, coating and cleaning (manual cleaning and mechanical cleaning),
Inspection, drainage, gasket, arc radius, spring, thread, dead angle, adhesive part, non-product contact surface requirements, all-round requirements of producer quality system, etc.
