How to distinguish the normal floating rust and rusting of astm a242 steel plate

The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced astm a242 steel plate production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, astm a242 steel plate steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

A709Gr50 steel is a high-strength low-alloy stee. It is widely used in engineering structures, such as building steel structures, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for those requiring good weldability and toughness Construction and construction machinery parts. BBNsteel’s engineers suggest customer choose low temperature impacting test for steel A709 grade 50 at zero centigree, because these steel plates A709Gr50 normally used in this temperature.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. astm a242 steel plate, 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.

astm a242 steel plate, S355j2g3 steel plate is a kind of main atmospheric corrosion-resistant steel, s355j2g1w steel plate is a kind of weathering structural steel, its mechanical properties are similar to s355j2g2. By adding CR, Cu and Ni, the oxide layer is firmly attached to the workpiece surface. This oxide layer prevents further corrosion of the steel.

astm a242 steel plate, Q355GNH weather resistant steel plate is one of our main product, it is belong to the weather resistant steel plate. We can supply the different sizes of Q355GNH weather resistant steel plate. And the rolling size of Q355GNH weather resistant steel plate is following: the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the Q355GNH weather resistant steel coil thickness should not exceed 25 mm.

We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, astm a242 steel plate A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the astm a242 steel plate steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.

Our company will accept the product quality objection registration record, pass it to the astm a242 steel plate production unit and relevant departments, and timely coordinate the supervision of product astm a242 steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
