What are the top five SMA490CW steel channel hot rolled plates mills in Myanmar

Our company was founded in 2000, which initially committed to providing high-quality steel SMA490CW steel channel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export SMA490CW steel channel steel to the international market, opening up the international steel market.

Manganese steel vs carbon plate
Manganese steel and ordinary steel belong to carbon structural steel and low alloy structural steel. The difference between manganese steel and SMA490CW steel channel is different in compressive strength, strength and main purpose. In terms of compressive strength, the compressive strength of manganese steel is higher than that of ordinary steel plate. In terms of strength, the strength of manganese steel is also higher than that of carbon steel, and in terms of application, manganese steel plates have more prominent advantages due to the advantages of materials, so the application areas are more common.

The five advantages of SMA490CW steel channel wear-resistant steel plate can reduce its own weight. The steel plate is designed according to the addition of several required alloy elements. Through the special heat treatment method of steel plate, the strength level of SMA490CW steel channel steel plate is improved to make it have high hardness (wear resistance) corresponding to various specifications. The result is a significant reduction in the weight of the structure.

The common delivery status of SMA490CW steel channel, SA516 Gr 70 plate is as follows:
1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point.
2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air).
3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly.
4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.

Heat treatment specification and microstructure of SMA490CW steel channel, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling. Microstructure: bainite + ferrite.Mechanical properties of 12Cr1MoV alloy plate:Tensile strength σb (MPa)：≥490(50); Yield strength σs (MPa)：≥245(25); Elongation δ5 (％)：≥22; area shrinkage ψ (%): ≥ 50; Impact energy Akv (J): ≥ 71; Impact toughness value αkv (J/cm2)：≥88(9).
