Technical key points of A515 grade 70 pressure vessel steel sheet production

ASTMA335 steel pipe of grades P23,P91, P92, P122, and P911 shall be reheated and furnished in the full-annealed, isothermal annealed,or normalized and tempered condition. If furnished in the normalized and tempered condition, the minimum tempering temperature for Grades P5, P5b, P9, P21, A515 grade 70 pressure vessel steel sheet product and P22 shall be1250°F [675°C], the minimum tempering temperature for Grades P1, P2, P11, P12, and P 15 shall be 1200°F [650°C].

The company now has A515 grade 70 pressure vessel steel sheet oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than A515 grade 70 pressure vessel steel sheet 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the A515 grade 70 pressure vessel steel sheet steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

A515 grade 70 pressure vessel steel sheet, EN 10025 E355 steel plate / sheet is suitable for general building steel. Chemical composition and mechanical properties of EN 10025 E355 steel. EN 10025 E355 steel conforms to EN 10025 standard, equivalent to DIN 17100: ST60-2, NFA: a60-2, UNI 7070: FE590 steel grade.
