Reliable supplier of SPA-H weathering steel plate

The use of low carbon steel is limited due to its low strength. The strength of the carbon steel can be greatly improved by properly increasing the manganese content in the SPA-H weathering steel plate carbon steel and adding some alloy elements such as vanadium, titanium and niobium. If the carbon content in the carbon steel is reduced and a small amount of aluminum, boron and carbide forming elements are added, the ultra-low carbon bainite can be obtained, SPA-H weathering steel plate which has high strength and good plasticity and toughness.

The company has allocated special environmental protection facilities for all SPA-H weathering steel plate pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, SPA-H weathering steel plate steel mill scale, environmental protection dust has reached 100%.

The company currently has a number of extended steel processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment, and can provide customers with diversified products and services. In addition, the company has strong technical force, complete production equipment and advanced production technology. The testing methods are perfect and the SPA-H weathering steel plate product quality is high.

The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of SPA-H weathering steel plate, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
