Quality Assurance:

1. We will strictly inspect our production that we sold according to the customer’s request.

2. Our steel reaches international quality standards.

3. Quality should be in conformity with the specification of the manufacturer. Quantity and packing conditions should be in conformity with the term in the contract.

4. Should the packing found damaged, the buyer has the right to claim to the seller

 "Steel alloy in addition to iron, carbon, the addition of other alloy elements, called alloy steel. In the ordinary carbon steel on the basis of adding one or more moderate alloy and iron carbon alloy. The special properties of high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance and non magnetism can be obtained according to the different adding elements.
Many kinds of alloy steel, usually alloy element content how many points for low alloy (content of less than 5%) and in (the content of 5% ~ 10%) steel, high alloy steel (content > 10%); according to the quality points according to the high-quality alloy steel, the characteristics of alloy steel; according to the characteristics and uses and alloy structure steel, stainless steel, acid resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel and special properties of steel, such as soft magnetic, permanent magnetic steel, non-magnetic, etc..
In the process of steel making, manganese is a good agent for the removal of sulfur and sulfur, and manganese in steel is 0.50% to 0.30. In plain carbon steel to join more than 0.70% even manganese steel, than the average amount of steel of steel not only enough toughness and have higher strength and hardness, improve the quenching of steel, steel to improve the performance of thermal processing, such as 16Mn steel A3 than the yield point is up to 40% of. Wear resistance high manganese steel 11 - 14%, for the excavator bucket, ball mill liner. The increase of manganese content, reduce the corrosion resistance of steel, reduce the welding performance."
