A131 FH40 ship construction steel stainless steel

SA516 Gr65 sheet is a carbon steel plate for medium and low temperature pressure vessels. It implements the ASME standard of the American Standard. It can provide a minimum thickness of 8mm and a width of 1500~4000mm. The A131 FH40 ship construction steel product thickness direction (Z-direction) resistance to tearing and wet hydrogen sulfide corrosion can be added Performance (HIC+SSCC) steel. Steel used to manufacture pressure vessels for petrochemical, gas separation and gas storage and transportation equipment.

The company specializes in the research and development, production and sales of A131 FH40 ship construction steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has A131 FH40 ship construction steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A131 FH40 ship construction steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

"Mirror" refers to the surface state of A131 FH40 ship construction steel stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in A131 FH40 ship construction steel steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of A131 FH40 ship construction steel steel.

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.
