1.There should be no cracks, scars, folds, air bubbles, inclusions, and visually visible delaminations on the surface of X52 steel plates that are harmful to us
The basic production processes of API 5L X60 pipeline steel mainly include: conventional semi-continuous hot rolling, CSP continuous casting and rolling, medium
Q690D belongs to low-alloy high-strength structural steel, and Q690D can also be called low-temperature-resistant high-strength steel with a yield strength of 6
According to the properties of Q690 steel, the author summarizes the following key points of the welding process:
1.Preheating work. The structural parts of the
In order to obtain good mechanical properties, many high-strength steels use a combination of multiple heat treatment methods. For Q690 steel, the suitable heat
The difference between hot rolling and cold drawing of A53 steel is the difference in production process. The hot rolling of A53 steel is processed at high temp
1. Raw materials
The raw material of A106 steel pipe is steel billet. When making A106 cold-drawn steel pipe, the billet should be dried firs, this is to remove
ASTM A53 is Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless.ASTM A106 is Standard Specification for Seamless Carb
A285 carbon steel is generally considered to be weldable using common welding techniques such as shielded metal arc welding (SMAW), gas tungsten arc welding (GT
A285 grade C is a carbon steel plate used primarily in pressure vessel applications. The thickness range of A285 grade C plate varies depending on the intended
The carbon content of S690QL steel plate does not exceed 0.2%. Due to the strengthening effect of alloy elements, the hardenability of weld seam and welding hea
S690QL steel plate is a high-strength low-alloy steel, commonly used in the manufacture of heavy machinery and equipment, S690QL steel plate is also widely used
Pickling: The process of using acid solution to remove scale and rust on the surface for S690QL steel plate is called pickling. It is a method of cleaning the m
The standard thickness tolerance for steel sheet Q235 varies depending on the specific standard that is being used and the thickness range of the sheet.In China
Steel Q235B is not corrosion-resistant. It is a low carbon structural steel with good strength and durability, but it is prone to corrosion in certain environme
In order to produce high-quality S500MC steel, every step has strict requirements. Let's briefly understand the production process of S500MC steel and focus
