What is the role of penetration testing in EN S420ML steel price cutting

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, EN S420ML steel price based on a high starting point and high technology, the company has vigorously developed various steel products EN S420ML steel price and deep-processed parts, steel structures, precision castings, seamless pipes.

SAE4340, same as UNS G43400. Tensile strength σb ≥980(100) Yield strength σs ≥835(85), used to manufacture important parts with high strength and good plasticity. After nitriding treatment, make important parts with special functional requirements, such as shafts, gears, and gears. Firmware etc. Delivery EN S420ML steel price in heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment.

EN S420ML steel price, 09CuPCrNi-A corrosion-resistant steel plate belongs to ordinary low-alloy steel and steel for engineering structures; it is a high-strength corrosion-resistant steel plate. The combination of Cu and P can resist atmospheric corrosion. In addition, there are Cr and Ni, both of which are used in stainless steel. 09CuPCrNi-A corrosion-resistant steel plate is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.

The adhesive wear of EN S420ML steel price, wear-resistant plate refers to the relative sliding of the contact surface between the workpiece and the workpiece. Due to the effect of solid-phase welding, the adhesive point is separated from the material matrix and transferred from one surface to another under the effect of shear force, resulting in the wear of the workpiece. Abrasive wear of wear-resistant plate refers to the phenomenon that external hard particles make the surface materials fall off in the process of friction and wear. There is also a case that there are hard convex particles on the surface of the workpiece, which can also play the role of abrasive in the process of friction and wear, resulting in surface spalling.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of EN S420ML steel price, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
