On 18th December, 2019, BBN Group decorated the office SA514 Grade A, B, E, F asme alloy steel building with many kinds of pendant. There were christmas trees, gifts and snowflakes in the logo wall. At the same time, we made a video at the Zhengzhou office to celebrate the coming Christmas holiday. Our SA514 Grade A, B, E, F asme alloy steel oversea sales team and market delevopment team wish you Merry Christmas and Happy New Year. Besides, we prepare some meaningful gifts for our old customers.
As the tungsten content increases, the strength and toughness of the NM360 wear-resistant steel plate increase. When the mass fraction of tungsten exceeds 1.06%, the toughness decreases due to the increase in the amount of carbide precipitation. This is because tungsten combines with carbon atoms in the NM360 wear-resistant plate to form a short-range ordered C-w atom pair bond structure. The C-w atomic bond is stronger than the C-Mn and C-Fe atomic bonds. Therefore, after adding tungsten to the NM360 wear-resistant steel plate, cracks will be formed, and the energy required to break the atomic bond will be greatly increased. The toughness and strength of SA514 Grade A, B, E, F asme alloy steel, NM360 wear-resistant steel plate treated with water toughening treatment will also be significantly improved.
SA514 Grade A, B, E, F asme alloy steel, 13CrMo44 steel plate is a kind of steel which with Cr, Mo,Cr-Mo and mainly used for pressure vessels. The steel grade 13CrMo44 is according to DIN 17155 standard which with the yield strength of 242MPa. The DIN 17155 13CrMo44 steel plate chemical composition is the content of C is 0.15, Mn is 2.00, S is 0.03, Cu is 0.30, Si is 1.00, P is 0.045, Cr is 17 or 19 and the Ni is 8 or 10.
