Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. Shell plates ASTM grade 36 of 8mx2mx8mm, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.
When the Shell plates ASTM grade 36 of 8mx2mx8mm thickness of the part is 14-20mm, the verticality of the section should not be greater than 12% of the thickness of the part.For their inspection mark, it is stipulated that: if the steel plate, section steel processing parts or stamping parts are inspected and qualified, the quality mark should be attached to prove that the inspection is qualified.
Steel transportation because of the special material of Shell plates ASTM grade 36 of 8mx2mx8mm steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
Shell plates ASTM grade 36 of 8mx2mx8mm, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.
