Q960 quenched and tempered steel grade classification: Q960C, Q960D, Q960E, Q960F. The product A588 grade K structural steel plate thickness is not more than 150MM. Q960 quenched and tempered steel has high yield strength and tensile strength, and its resistance to brittle failure is also great. Q960 quenched and tempered steel has excellent low temperature toughness, so it can be used in large welded structural parts and low temperature environments.
Q215 steel has good plasticity and weldability. Q235 steel has certain strength, plasticity, toughness and weldability. Q235 steel is easy to punch and can meet the use of steel structure. Q255 steel has high strength, good plasticity and weldability, and its application is not as extensive as Q235 steel. Q275 steel has high strength, poor plasticity and weldability. Q275 steel is used for shafts, connecting rods, gears, keys and metal components with high strength requirements.
Processing performance of quenched and tempered steel: A588 grade K structural steel plate plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.
The alloy steel plate is among our business scope, and it is one of our main product.
