The copper brittleness defects control of GL-A hot-rolled steel strip

Grade A ship steel is mainly used for the internal frame of the ship and the outer plate bearing general stress. Grade B, Grade D and Grade E ship steel GL-A hot-rolled steel strip can be used for important structures in high stress areas such as hull outer plate and main deck. The Grade E ship steel has good low temperature performance, which is suitable for the hull outer plate, deck, etc. According to the minimum yield strength, the high-strength ship steel is divided into four grades: A, D, E and F. The commonly used high strength ship steels are AH32, DH32, EH32, etc.

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of GL-A hot-rolled steel strip boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with GL-A hot-rolled steel strip high-end steels and competitive price.

"Mirror" refers to the surface state of GL-A hot-rolled steel strip 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.

The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the GL-A hot-rolled steel strip, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.

Our quality and service commitment: GL-A hot-rolled steel strip product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
