ASTM A242 has 2 grades: Type 1 and Type 2, while type 1 is the most used structural steel grade. Usually 100mm GL-A40 quenched and tempered steel it is produced to be hot rolled state, it is suitable for cutting, forming, drilling and machining, grinding.
The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, 100mm GL-A40 quenched and tempered steel seamless steel pipes for ships and petroleum cracking 100mm GL-A40 quenched and tempered steel steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many 100mm GL-A40 quenched and tempered steel products have been exported to the Middle East, India, Southeast Asia and Europe and America.
"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, 100mm GL-A40 quenched and tempered steel Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach 100mm GL-A40 quenched and tempered steel 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual 100mm GL-A40 quenched and tempered steel production capacity: 3.5 million tons."
A small amount of Nb is sufficient to obtain excellent comprehensive properties of 100mm GL-A40 quenched and tempered steel etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
