GB/T 4171 Q310GNH grade steel sheet/coil specification

GB/T 4171 Q310GNH grade,Over the years, the company has established a standard of steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating. Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum. The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures.

The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 ° High hardness and good oxidation resistance The new clad wear-resistant plate has multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance,GB/T 4171 Q310GNH grade.

In order to improve the corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.GB/T 4171 Q310GNH grade

We exported 2150 Tons SG295 steel coils to Sudan. The Sudan customer is LPG cylinder manufacturer. Before our cooperation, he usually purchased SG295 steel coils from UAE and Turkey. And he got to know our company through our regular customers in Uganda, UAE, and his friends in China. Then he gave us the order. We invited the customer to visit us before contract, but he insisted to visit us when the goods are finished production. After inspecting the size, package in workshop and witness the lab test for the SG295 steel coils, the customer was very satisfied to our quality control and professional arrangement.

16Mo3 alloy are featured by the good heat resistance and corrosion resistance. 16Mo3 steel plate chemical composition(%):C: 0.12 ~ 0.2 Si: ≤0.35 Mn: 0.4 ~ 0.9 P: ≤0.025 S: ≤0.01 Cu: ≤0.3 Ni: ≤0.3 Cr: ≤0.3 Mo: 0.25 ~ 0.35 Al: ≥0.02 N: ≤0.012. 16Mo3 alloy steel mechanical properties:Yield strength (MPa) 372MPa, Tensile strength (MPa) 350MPa, Elongation (%) ≥22. Impact temperature (℃) 20, Impact energy value (J) 335J / cm². 16Mo3 steel plate is widely used in petroleum, chemical, power station, boiler and other industries.

Safety production is the cornerstone of enterprise survival and development The company has passed OHSAS18001 occupational health and safety management system certification The company established a safety management network, which achieved clear powers and responsibilities, clear responsibilities, effective management and control, and provided organizational guarantee for safe production The company strictly complies with the "Environmental Protection Law", establishes an effective environmental protection emission control system and waste gas, waste water, waste solid recycling system, and makes great efforts to harden, lighten, green, and beautify the plant, and strive to build green steel enterprises,GB/T 4171 Q310GNH grade.
