The application of laser processing technology in processing of SA633 grade D carbon steel plate sheet

Cold-rolled sheet is mainly used in the manufacturing of household appliances, automobiles, agricultural machinery, etc., as well as the raw material for the base plate of galvanized sheet and tin-plated sheet and thin-wall welded pipe. For stamping grade cold rolled sheet, deep drawing, extra deep drawing and ultra deep drawing grade cold rolled sheet, the steel grades are Q195, Q215, Q235, SPCC, St12, St13, St14. Cold rolled plate: SPCCT-SD, SA633 grade D carbon steel plate sheet, SPCC, SPCE, DC01, DC03, DC04, DC05.

20 to 26mm thick SA633 grade D carbon steel plate sheet product BBN steel supply: 20*3000*5000, 20.5*2370*7000, 21*1960*7950, 22*1800*8000, 22*1500*6000, 22*1500*6050, 22.5*1680*8450, 22*1300*4000, 22*2600*9000, 22*1800*9000, 22.5*2560*7150, 23.5*2560*7150, 25*1460*4000, 23*3000*11980, 23*2480*8450, 23*2650*6000, 24*1560*6200, 25.5*2330*8300, 23*3000*12000, 23.5*2080*8100, 23*2650*6550, 26*3010*8100.

Medium thick steel plate refers to the steel plate with a thickness of not less than 3 mm but less than 20 mm. It can be produced by reversible hot rolling medium and heavy plate mill, and its thin products can also be processed by cold rolling mill. SA633 grade D carbon steel plate sheet, Medium thick steel plates are mainly used in boilers, shipbuilding, railway cars, automobiles, containers, military industry, national defense, construction, bridges and containers.

The European Iron and Steel Industry Union (Eurofer) has sent a letter to the president of the European Commission, asking the Commission to review the existing trade safeguard measures immediately, proposing to reduce the steel import quota by 75% within six months to help the European steel industry cope with the current difficult situation; For imported steel exceeding the quota, the tariff rate can be reduced to less than 25%. Europe has also proposed restrictions on SA633 grade D carbon steel plate sheet and so on steel imports related to crisis and safety.
