Why astm a656 grade 80 welding is generally not heat treated

The company attaches great importance to systematic management, and has passed the astm a656 grade 80 welding ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on astm a656 grade 80 welding quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Because 15CrMo steel contains high content of Cr, C and other alloying elements, the hardening tendency of steel is obvious and the weldability is poor. 15CrMo steel plate is used in petroleum, petrochemical, high-pressure boilers, etc., seamless pipes for special purposes include seamless pipes for boilers, seamless steel pipes for geology, seamless pipes for petroleum, etc. Welcome to contact us for astm a656 grade 80 welding product price in 2020.

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel astm a656 grade 80 welding surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

astm a656 grade 80 welding, API 5L X60 steel plate is one mainly of Steel for large diameter pipes, API-X60 steel for the manufacture of buried pipelines for transporting natural gas can succumb to severe degradation due to corrosion by the soil through. The types of corrosion of steel that can be produced are often general corrosion and pitting.

astm a656 grade 80 welding, 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar.
