316 stainless Steel Plate

The corrosion resistance, and high temperature strength of 316 stainless steel have been greatly improved due to the addition of Mo element. The high temperature resistance can reach 1200-1300 degrees and can be used under harsh conditions.

316 stainless steel plate characteristics:

Due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and can be used under harsh conditions; Excellent work hardening (non-magnetic); Excellent high temperature strength; No magnetism in solid solution state; Cold rolled products have good gloss and beautiful appearance; Compared with 304 stainless steel, the price is higher.

316 stainless steel plate purpose:

Equipment used in seawater, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.

National standards：

316 stainless steel plate has ideal microstructure after suitable solution treatment α/γ A biphasic structure with a ratio of about 50 / 50. When the solid solution temperature is above 1050 ℃, the number of ferrite phases in steel will increase with the increase of temperature, but due to the high nitrogen content, the phase proportion of steel below 1300 ℃ will not change significantly. If the steel is not aged at different temperatures (or affected by heat), it will α+γ There will be on the substrate γ 2 formation and δ、χ、 R、 α` Intermetallic phase and Cr2N and other oxides precipitate. Because the carbon content in steel is low (generally 0.01% - 0.02%), there is generally no carbide in steel.
