hot rolled SA709 Gr 50W carbon steel plate sheet channel

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, SA709 Gr 50W carbon steel plate sheet steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and SA709 Gr 50W carbon steel plate sheet carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

Both 20# seamless steel pipe and 20G seamless steel pipe are carbon structural steel with average carbon content of 0.20%. There are big differences in the use standard, chemical composition, mechanical properties and price between SA709 Gr 50W carbon steel plate sheet, 20# seamless steel pipe and 20G seamless steel pipe, so they must be selected correctly in the design and use, so as to avoid affecting the service life or even causing destructive accidents. The purpose of SA709 Gr 50W carbon steel plate sheet, GB8162 20# seamless steel pipe is for general structure, the purpose of GB8163 20# seamless steel pipe is for conveying fluid, and the purpose of GB3087 standard 20# seamless steel pipe is for low and medium pressure boiler. 20G seamless steel pipe is used for high pressure steam boiler and pipeline.

The advantages of SA709 Gr 50W carbon steel plate sheet, carbon steel: First of all, the price of carbon steel is low. Compared with stainless steel, galvanized steel, alloy steel, etc., the carbon steel has a great advantage in price. It is a good choice for manufacturers and merchants such as construction sites that use building materials in large quantities. Secondly, the carbon steel is easy to process. In the early days, steelmaking technology was underdeveloped. It was very difficult to manufacture high-precision steel, and carbon steel is widely used.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than SA709 Gr 50W carbon steel plate sheet. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel SA709 Gr 50W carbon steel plate sheet is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with SA709 Gr 50W carbon steel plate sheet SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.
