Is SA573 Gr 70 carbon steel plate sheet and tool steel the same?

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of SA573 Gr 70 carbon steel plate sheet boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with SA573 Gr 70 carbon steel plate sheet high-end steels and competitive price.

SA573 Gr 70 carbon steel plate sheet, 45# steel is carbon steel, belonging to high strength medium carbon quenched and tempered steel, with carbon content of 0.45%, so it is called 45# steel. 45# steel does not contain specially included alloy elements. SA573 Gr 70 carbon steel plate sheet, 45# steel is one of the most widely used high-quality structural steel. 45# steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

As a new type of coil material, compared with the traditional steel coil, SA573 Gr 70 carbon steel plate sheet, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.

The final heat treatment of quenched and tempered alloy steel, SA573 Gr 70 carbon steel plate sheet is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
