Today, a friend said that he wanted to order anchor bolts, saying that he wanted L-shaped anchor bolts. Our general anchor bolts are ordinary grade anchor bolts made of Q235 material, but the friend said that he wants 8.8 grade anchor bolts, this grade belongs to the standard of high-strength bolts, so it is ordinary The Q235 material cannot meet his requirements, so China Custom Bolt Wholesaler uses 45 steel to solve the problem of its strength level.

If 45 steel is used, its material is different. 45 steel can be made with higher hardness, so the price will be higher than ordinary Q235 material. Speaking of this, it brings up a topic of bolt material hardness. Many users have strict requirements on the hardness of bolt Bunsen. Because these bolts or anchor bolts will be used in various equipment. The requirements are different. In some cases, if there is no requirement for hardness, ordinary hardness materials can be used to produce and process anchor bolts, so as to avoid the situation of oversized materials. If users say that they must use anchor bolts of 8.8 or above, then the use of No. 45 steel requires heat treatment, and of course the cost will go up. The situation of different manufacturers is different. Some manufacturers may not have other materials in stock, so they can only use No. 45 steel for production and processing. But if some manufacturers have some other materials, they may be able to solve the problem. If the torque requirement can satisfy the user, then the material should be at least 1018.

When using , communicate with users as much as possible. This can avoid problems after use.
