Do you know the API 5L Grade B (L245) steel materialyield strength?

The company has allocated special environmental protection facilities for all pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, steel mill scale, environmental protection dust has reached 100%,API 5L Grade B (L245) steel material.

A572 gr42 steel plate is a kind of main precision steel structure and normalizing steel. API 5L Grade B (L245) steel material, ASTM A572 gr42, 50, 55, 60, 65 is a kind of high strength low alloy steel plate, which is widely used in factory construction, general buildings and various construction machinery, such as mining and various construction drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, hydraulic supports, mining machinery and other structures.

API 5L Grade B (L245) steel material,There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products API 5L Grade B (L245) steel material are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.
API 5L Grade B (L245) steel material

The preparation of galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
