ASTM equivalent of P275NL2 pressure vessel steel sheet

Q690C steel plates are mainly used in heavy machinery, marine engineering, metal structures. BBN STEEL cooperated with Wugang to produce Q690C steel for use in its enterprise production and construction projects. The prospects for produts exporting to the United States, Canada, Australia, India, and Europe are promising. More than 10,000 tons P275NL2 pressure vessel steel sheet products have been directly supplied to European customers.

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, P275NL2 pressure vessel steel sheet quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the P275NL2 pressure vessel steel sheet International leading steel materials supplier.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched P275NL2 pressure vessel steel sheet increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of P275NL2 pressure vessel steel sheet during tempering, while tempering determines the performance and life of the workpiece.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of P275NL2 pressure vessel steel sheet etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
