Alloy steels or high strength steels are low carbon steels or steels at the lower end of the medium carbon range. Alloy steels have additional alloying components to increase their strength, wear resistance or especially tensile strength. These alloying components include chromium, molybdenum, silicon, manganese, nickel and vanadium. The maximum permissible content of impurities such as phosphorus or sulfur is limited.

We play a major role in providing our customers with a high quality range of alloy steel grade 2H lock washers with some great features such as precise dimensions, custom solutions, robustness and more.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

It exhibits exceptional corrosion resistance in chemical environments containing phosphoric acid, nitric acid, chlorides and sulfuric acid. It also has good mechanical properties at both ambient and elevated temperatures.

Chromium molybdenum has a better strength-to-weight ratio than steel, which enables designers to use thinner walled tubing or smaller diameter tubing to reduce overall weight.

A335 P91 material, we use ASTM A335 Gr P91 Welded Pipe
Heat treatment method to standardize the strength of the material. 9% chromium and 1% molybdenum make the pipe strong and corrosion resistant. The material is resistant to wear and high temperature creep. ASTM A335 P91 pipe does not deteriorate, reduces thickness, and has higher creep strength. Pipeline applications are primarily used in power generation, petrochemical, heater and reheat liners, boilers, and petroleum services.
