Low-alloy structural steel plates are mainly used in machinery manufacturing and metal structural parts. Advantages of A633Gr.D hardness, low-alloy structural steel plates: They have superior performance and light weight. Disadvantages of low-alloy structural steel plates: These steel plates are all killed plates. The molten steel is deoxidized before the production. When the molten steel is poured into the ingot mold, its reaction is relatively calm and there will be no boiling state. A633Gr.D hardness, low-alloy structural steel plates price will be more expensive.

A633Gr.D hardness, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of A633Gr.D hardness metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.
