Is astm a573 gr 70 and tool steel the same?

The company adheres to the astm a573 gr 70 business tenet of "integrity casting strength, cooperation creating win-win", takes value-added service of supply chain as the tenet, and under the premise of existing market, bulk trade, logistics distribution and other advantages, develops a new comprehensive steel industry model combined with informatization. And will continue to provide customers with high-quality steel products and good service. We sincerely welcome new and old customers to join hands with our company astm a573 gr 70 and seek common development!

Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, astm a573 gr 70. The main differences according to the classification are as follows: A needs no impact test, B needs room temperature impact test (20 degrees above zero), C needs zero degree impact test, D needs minus 20 degree impact test, and E needs minus 40 degree impact test. The most important characteristic of manganese steel plate is that under the condition of strong impact and extrusion, the surface layer rapidly hardens, but the core still maintains good toughness and plasticity, and the hardened layer has good wear resistance.

The wear-resistant layer of astm a573 gr 70 wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy astm a573 gr 70 carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of astm a573 gr 70, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.

SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to astm a573 gr 70 ASTM A36, which is widely used in engineering and industrial applications. The cost of JIS SS400 steel angle steel structure is low, and it has good performance in major projects. SS400 angle steel description:Item: SS400 angle steel. astm a573 gr 70 Standard: JIS G3101-2004. Technology: hot rolled. Type: equal & unequal. Surface: black or galvanized. Length: 6 m, 9 m, 12 m or per your request. Equal angle: Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 to 20 mm. Length: 6 m, 9 m, 12 m or per your request. Unequal angle: Size: 30 × 20 mm to 250 × 90 mm. astm a573 gr 70 Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, astm a573 gr 70 and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

Our company will accept the product quality objection registration record, pass it to the astm a573 gr 70 production unit and relevant departments, and timely coordinate the supervision of product astm a573 gr 70 quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
