The company is a leading company that sells steel plate products in the Central Plains region and has a high reputation in the steel plate industry Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold steel products with various materials The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries,A573 Gr 70 plate.
A573 Gr 70 plate,17MN4 steel plate, , DIN 17135 17MN4 steel plate is a kind of material for boiler and pressure vessel steel. DIN 17135 17MN4 steel plate is characterized by a minimum yield strength of 220 - 295 MPa and by good weldability, so 17MN4 steel is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids.A573 Gr 70 plate
A573 Gr 70 plate,The main characteristics of A573 Gr 70 plate, 12Cr1MoV alloy steel plate are as follows:Compared with 12CrMoV steel, 12Cr1MoV alloy steel plate has higher oxidation resistance and thermal strength The creep limit of 12Cr1MoV steel is close to the stress rupture strength, and it has high plasticity under the condition of long-term tension The process and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress relief treatment is required after welding,A573 Gr 70 plate.
The steelmaking furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the internal quality of the steel.
A573 Gr 70 plate,St52-3 steel is a low alloy, high strength structural steel which can be readily welded to other weldable steel. St52-3 steel’s mechanical properties is yield strength more than 355 MPa, tensile strength 490-630Mpa. For St52-3 steel, the C element content is 0.24%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.045% max, the S element content is 0.045% max.
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.
