Alloy Steel Nuts And Bolts

When the customer specifies a certain grade of material, if we do not have this material in stock or it is not easy to purchase in the market, we will ask the customer what the alloy steel bolts and nuts will be used for and make a written request to replace it with an equivalent material that meets the mechanical performance requirements.

Alloy Bolts And Nuts by Datian

1. low carbon martensitic alloy steel C%> 0.25%. Low carbon martensitic steel is currently commonly used 20MnTiB and so on.

2. Medium carbon alloy steel: adding alloying elements to ordinary carbon steel to increase some special properties of the steel, such as the most used alloy steel: 40Cr, 35GrMo, 35VB. The increase of alloying elements in alloy steel improves the hardenability and strength and also improves the use conditions of high-temperature resistance, low-temperature resistance, and corrosion resistance of alloy bolts and nuts Note: Pre-annealing required.
