supply 09cuptire-a tempering temperature

Q370R grade is a Chinese steel material for boilers and pressure vessels. "Q" means yield strength, "370" means yield value, and R means container. Delivery status of Q370R steel plate: normalizing -20℃ impact. The steel product supply 09CUPTIRE-A can also be subjected to controlled rolling treatment or normalizing treatment according to the requirements of the manufacturer or design. The Q370R plates thickness are produced with up to 150mm.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. supply 09CUPTIRE-A, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, supply 09CUPTIRE-A, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

It is a modern high-tech professional enterprise integrating scientific research, supply 09CUPTIRE-A production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as supply 09CUPTIRE-A process technology development, technology transfer and related technical consulting and technical services.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
