Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business S460M mechanical properties department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and S460M mechanical properties after-sales service department constitute the service customer network.
ASME S460M mechanical properties delivery status: thickness ≤40, hot rolled or normalized; thickness >40, normalizedAccording to the different tensile strength of the material, ASME SA204 steel is divided into three strength grades: A, B, and C, namely SA204GrA, SA204GrB, and SA204GrC. The maximum thickness of steel plates corresponding to these three grades is limited to:SA-204A large plate thickness does not exceed 150mmSA-204B large plate thickness does not exceed 150mmSA-204C large plate thickness does not exceed 100mm
The wear-resistant plate S460M mechanical properties shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and S460M mechanical properties hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.
The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, S460M mechanical properties.
Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with S460M mechanical properties, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
We have our own factory, including the production and manufacturing of steel pipes, with a special S460M mechanical properties steel pipe manufacturer and storage warehouse.
