Stainless steel is a metal material with excellent corrosion resistance. It is widely used in various fields, especially in the construction, chemical industry, food processing, and other industries. Among them, 304 stainless steel is the most commonly used material. It has excellent corrosion resis

Stainless steel pipes are an important material widely used in modern industry. They have the advantages of corrosion resistance, high strength, and high-temperature resistance. They play an important role in construction, chemical industry, medicine, food processing, and other fields. As a common s

42CrMo alloy steel pipe is a high-quality steel material, which is widely used in various fields with its excellent mechanical properties and durability. It is made of 42CrMo alloy steel, which has good hardness, strength, and corrosion resistance, and is suitable for use under harsh working conditi

Steel pipes, as an important building material, are widely used in all walks of life. When purchasing steel pipes, different application scenarios have different requirements for the wall thickness of steel pipes. Among them, the wall thickness of 120 steel pipes is a common parameter. First, the

Plastic-coated seamless steel pipe is a steel pipe with excellent anti-corrosion performance. Based on steel pipe production, a layer of plastic is coated on the surface of the steel pipe through a special process. This special plastic coating process gives the steel pipe excellent anti-corrosion ab

Stainless steel precision steel pipe is called precision steel pipe because it has high precision, good tolerance control range, uniform wall thickness, smooth inner wall, no lines, and surface roughness is smoother than ordinary pipes. Below, we will take you to understand the surface roughness of

Round stainless steel pipes and square steel pipes are very common in life. Whether it is a national standard or a non-standard part, the amount of stainless steel used in these two shapes is comparable. There are still differences between round stainless steel pipes and square steel pipes, and it i

1. Does vacuum heating cause quenching and carbonization? When analyzing the carbonization phenomenon of vacuum heat treatment workpieces, there are two misunderstandings: one is that the workpiece is carbonized in the quenching oil; and the other is that the graphite parts in the heating chamber a

1. Introduction to Q390B steel plate: Q390B is a low-alloy high-strength structural steel. Q390B is not only a high-strength steel, but also a low-carbon steel. Q390B has high yield strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performanc

Choose a suitable site and warehouse 1) The site or warehouse for storing steel should be clean and well-drained, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed from the site to keep the steel clean; 2) Steel should not be piled together wi

The production process of hot-rolled solid ingots is to roll them into hollow tubes with no seams around them. Carbon steel, alloy tubes, high alloy steel, and some non-ferrous metal seamless steel pipes can be produced by hot rolling, with an outer diameter range of 16 to 1600 mm and a wall thickne

The finishing process of steel pipe is an important process to remove steel pipe defects, further improve the quality of steel pipes, meet the needs of special uses of products, and clarify the "identity" of products. Steel pipe finishing mainly includes steel pipe straightening, cutting ends (chamf

First, material characteristics of large-diameter internal and external plastic-coated steel pipes: 1. Plastic coating layer: The inner and outer layers of large-diameter internal and external plastic-coated steel pipes are protected by plastic coating. This coating has good corrosion resistance an

In the modern petrochemical industry, the application of seamless steel pipes is becoming more and more extensive. Among them, the seamless steel pipe for oil cracking No. 20 has become the leader in the industry with its excellent performance and wide application fields. This article will discuss t

First, surface processing grades, characteristics, and uses - Original surface: NO.1 The surface is treated with heat and pickling after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc., with a thicker thickness of 2.0MM-8.0MM. - Blunt su

Steel bending pipe processing forming process 1. Die forging. For socket welding and threaded tees, crosses, elbows, and other small pipe fittings, the shapes are more complicated and should be manufactured by the die forging process. The die forging blank should be a rolled profile such as a bar,
