Welding s355j2 n low alloy steel plate steel equivalent grades

Q420q material is a kind of structural steel plate for bridges, and there are three quality levels Q420qD, Q420qE and Q420qF. When the Q420q plate is required to have the performance in the thickness direction, the symbols Z15, Z25, Z35 representing the performance level in the thickness direction are added after the above-mentioned grades. Namely Q420qDZ15, Q420qDZ25, Q420qDZ35, Q420qEZ15, Q420qEZ25, Q420qEZ35, Q420qFZ15, Q420qFZ25, Q420qFZ35.

Cold-rolled s355j2 n low alloy steel plate steel plates are used for parts that require a large degree of plastic deformation of the material when forming parts, and there must be no wrinkles, cracks, etc. on the surface. For different parts, use different grades of steel plates. For example, the Japanese automotive s355j2 n low alloy steel plate steel sheet standard is divided into three categories. The first category (SPCC) is ordinary cold-rolled steel sheet, which is usually rolled by rimmed steel, the second category (SPCD) is rolled steel sheet, and the third category (SPCE or SPCEN) ) Is a cold rolled steel sheet for deep drawing.

One person familiar with the situation said Germany's ailing ThyssenKrupp Group was in talks with its international counterparts to merge its loss making s355j2 n low alloy steel plate steel business. The talks will be announced Monday as part of a strategic reform that could include closing or selling assets. Previously, ThyssenKrupp steel Europe, Germany's largest steelmaker, announced a loss in the first half of the group three point seven two 100 million euros four point zero two Billion US dollars). ThyssenKrupp has continued to advocate the benefits of s355j2 n low alloy steel plate steel integration since it abandoned its joint venture with Tata Steel a year ago to sell its precious elevator division.
