Steel Sheets Alloy Steel Plate Supplier Thermal Properties

With the development of science, technology and industry, higher requirements
are put forward for materials, such as higher strength, resistance to high
temperature, high pressure, low temperature, corrosion resistance, wear and
other special physical and chemical properties. To meet the requirements, alloy
steel plates appeared.

1.Alloy Steel Plate Performance Issues
With the development of science, technology and industry, higher requirements
are put forward for materials, such as higher strength, resistance to high
temperature, high pressure, low temperature, corrosion resistance, wear and
other special physical and chemical properties. fulfil requirements.
The performance of carbon steel mainly has the following shortcomings:
(1) Low hardenability Under normal circumstances, the maximum hardenable
diameter of carbon steel water quenching is only 10mm-20mm.
(2) The strength and yield strength are relatively low. For example, the σs of
ordinary carbon steel Q235 steel is 235MPa, while the σs of low alloy
structural steel 16Mn is more than 360MPa. The σs/σb of 40 steel is only
0.43, which is much lower than that of alloy steel.
(3) Poor tempering stability Due to the poor tempering stability, when carbon
steel is quenched and tempered, a lower tempering temperature is required to
ensure higher strength, so that the toughness of the steel is low; in order to
ensure better Toughness, and the strength is low when the high tempering
temperature is used, so the comprehensive mechanical properties of carbon steel
are not high.
(4) Can not meet the requirements of special properties Carbon steel is often
poor in terms of oxidation resistance, corrosion resistance, heat resistance,
low temperature resistance, wear resistance and special electromagnetic
properties, and cannot meet the needs of special performance properties.

2.The difference between carbon steel and alloy steel plate
The performance of carbon steel mainly has the following shortcomings:
(1) Low hardenability In general, the maximum hardening diameter of carbon
steel water quenching is only 10mm-20mm.
(2) The strength and yield strength are relatively low. For example, the σs of
ordinary carbon steel Q235 steel is 235MPa, while the σs of low alloy
structural steel 16Mn is more than 360MPa. The σs/σb of 40 steel is only

low temperature resistance, wear resistance and special electromagnetic
