Chong cold rolled carbon steel sheet and strip, equivalent to Chinese 08AL (5213) deep drawing steel. The need to ensure non-aging property, the N is added at the end of grade SPCEN. Cold-rolled carbon steel sheet and strip quenching Code: annealed state A, the standard quenching of S, 1/8 hard for 8,1 / 4 hard for 4,1 / 2 hard 2 hard one. Surface processing code: Matte finish is D, bright finish for B. SPCC-SD represents the standard quenched, usually with a matte finish of cold-rolled carbon sheet. Again SPCCT-SB represents the standard conditioning, light processing, cold-rolled carbon sheet to ensure that the requirements of the mechanical properties. (3) hot-rolled silicon steel sheet hot-rolled silicon steel plate, said DR 310s stainless steel plate, divided by the number of low silicon content of silicon (silicon content ≤2.8%), high-silicon (silicon content> 2.8%). Representation: DR + iron loss (with 50HZ repeatedly magnetized and by sinusoidal variation of the maximum magnetic flux density per unit weight of the iron loss when 1.5T) + 100 times 100 times thickness values. As DR510-50 iron loss value of 5.1 indicates a thickness of 0.5mm hot rolled silicon steel sheet. Household appliances, hot-rolled silicon steel sheet with a grade of iron loss by JDR + value + thickness value expressed as JDR540-50.304 stainless density 7.93 g / cm3 austenitic stainless steel is generally 304 with the value amount of chromium (%) 17.00 -19.00 stainless steel machining parts, nickel content.%) 8.00-10.00,304 equivalent to China's 0Cr19Ni9 (0Cr18Ni9) 304 stainless steel is a versatile stainless steel material, anti-rust performance than the 200 series stainless steel stronger. High temperature also better. 304 stainless steel with excellent corrosion resistance and good energy between resistance to intergranular corrosion. For oxidizing acid, in the experiment: the nitrate concentration ≤65% below the boiling temperature of 304 stainless steel with strong corrosion resistance. Most of the alkali solution and organic and inorganic acids also have good corrosion resistance of stainless steel plate processing punch, Jixian stainless steel plate, 20 years provided by the Tianjin Shengda Po-Po-Billion Trading Company.
