Classification of abrasion resistant steel plate
Abrasion resistant steel plate is widely used in machinery manufacturing, so what types of abrasion resistant steel plate are there?1. High manganese steelThe as-cast structure of high manganese steel is usually composed of austenite, carbide and pearlite
What are the differences between 42CrMo steel plate and 42CrMoA steel plate?
42CrMo steel plate and 42CrMoA steel plate both belong to the national standard high strength alloy structural steel.The implementation standard of 42CrMo steel plate is GB/T 3077-2015, and the implementation standard of 42CrMoA steel plate is GB/T 3077-1
The role of nickel, molybdenum and vanadium elements in steel
The role of nickel in steel1. It can improve the strength of steel without significantly reducing its plasticity;2. Improve the low temperature toughness of steel;3. Improve the workability and weldability of steel;4. Improve the corrosion resistance of s
Introduction of hot rolled steel plate and cold rolled steel plate
The mechanical properties of hot rolled steel plate are far inferior to those of cold working and forging, but they have better toughness and ductility.V Cold rolled steel plates have low toughness due to a certain degree of work hardening, but can achiev
Rust spot of weather resistant steel plate
The first stage: The weather resistant steel begins to grow small rust spots, the rust spots of ordinary steel plates are relatively loose, and some of the rust treatment is poor and even peels off the rust.The second stage: The weather resistant steel ha
Performance requirements of offshore platform steel plates
Because the offshore platform is immersed in seawater all the year round, it has to withstand various harsh sea conditions. Therefore, the technical indicators of offshore platform steel plates are extremely high, not only high atmospheric corrosion resis
Application and characteristic analysis of S355J0WP weather resistant steel plate
S355J0WP steel plate is a weather resistant steel plate, which is a low alloy steel series between ordinary steel and stainless steel. S355J0WP steel plate has the characteristics of high-quality steel such as strength and toughness, plastic elongation, f
A comprehensive introduction to stainless steel
Stainless acid-resistant steel is referred to as stainless steel. It is composed of two parts: stainless steel and acid-resistant steel. In short, steel that can resist atmospheric corrosion is called stainless steel, and steel that can resist chemical me
What are the advantages of NM400 abrasion resistant steel plate
The high-strength NM400 abrasion resistant steel plate has high strength and high fracture resistance, high impact strength and excellent abrasion resistance. The high-strength NM400 abrasion resistant steel plate has undergone a special heat treatment pr
How to distinguish weather resistant steel plate and ordinary steel plate
1. Corrosion resistance: Weather-resistant steel plates are corroded in natural climates, and a dense oxide layer is formed on the surface of the steel, which prevents oxygen and water in the atmosphere from penetrating into the matrix and plays a role of
Main uses of different grades of carbon structural steel
1. Grade Q195 steel plate has low carbon content, low strength, but has strong plasticity, good toughness, good processing performance and welding performance. Grade Q195 steel plate is used for rolling thin steel plate and wire rod. Cold-rolled and hot-r
Brief introduction of weather resistant steel plate SPA-H
SPA-H is a kind of weather resistant steel plate. The steel grade adopts Japanese steel grade SPA-H. Its chemical composition, mechanical properties, thickness and width deviations are required to comply with the Japanese standard JISG3125-2004 "High
Introduction of common steel cold and hot rolling
Wire: 5.5-40 mm in diameter, coiled, all hot-rolled. After being cold drawn, it is a cold drawn material.Round steel: except for the precision-sized bright material, it is generally hot-rolled, and there are also forged materials (with forging marks on th
What are the differences between hot rolled steel plates and cold rolled steel plates?
The hot rolled steel plates have low hardness, easy processing and good ductility. The cold rolled steel plates have high hardness and are relatively difficult to process, but they are not easy to deform and have high strength.Hot rolled steel plates have
