Welding technology of cold rolled 05CuPCrNi

The company operates Henan metallurgical rolling iron and steel factory all year round, providing steel products for various industries such as ow alloy high strength series, boiler and pressure vessel steel plate, power station engineering steel plate series, cold rolled 05CUPCRNI bridge structure steel plate, corrosion resistant steel plate, composite steel plate, high-rise building structure, die steel plate series, steel plate series for shipbuilding and offshore platforms, pipeline steel plate, alloy structure and other steel plates.

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, cold rolled 05CUPCRNI 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 cold rolled 05CUPCRNI International leading steel materials supplier.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < cold rolled 05CUPCRNI steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished cold rolled 05CUPCRNI product packaging.

The mechanical properties of cold rolled 05CUPCRNI, boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
