JIS G4305 SUS310S cold-rolled stainless steel plate boasts an impressive chemical composition that provides exceptional corrosion resistance and high-temperature strength. Its primary alloying elements are chromium (Cr) and nickel (Ni), with significant additions of silicon (Si). The detailed chemical composition of SUS310S, as per JIS standards, is as follows:

· Chromium (Cr): Approximately 25%

· Nickel (Ni): Approximately 20%

· Silicon (Si): Approximately 2%

This composition ensures the steel's ability to withstand oxidation and corrosion in a wide range of environments, particularly at elevated temperatures.

Mechanical Properties

The mechanical properties of SUS310S cold-rolled stainless steel plate make it suitable for applications requiring high strength and durability. Key mechanical properties include:

· Tensile Strength: High, suitable for demanding applications

· Yield Strength: Adequate to withstand heavy loads

· Elongation: Good ductility, enabling it to be formed into various shapes

· Hardness: Moderate to high, depending on the heat treatment process

The exact values of these properties may vary slightly based on the thickness and heat treatment conditions.

Heat Treatment State

JIS G4305 SUS310S cold-rolled stainless steel plate is typically supplied in a solution-annealed condition, ensuring optimal corrosion resistance and mechanical properties. Solution annealing involves heating the steel to a temperature above its critical point, holding it for a sufficient time to allow for complete dissolution of carbides and other precipitates, and then cooling rapidly to prevent re-precipitation. This process results in a microstructure that is both corrosion-resistant and mechanically stable.

Available Production Sizes

TJC Steel Group offers JIS G4305 SUS310S cold-rolled stainless steel plates in a wide range of sizes to meet various application requirements. Typical dimensions include:

· Thickness: From 0.3 mm to 3.0 mm

· Width: Up to 1600 mm (depending on the thickness)

· Length: Customizable to customer specifications

The plates can also be cut to specific sizes or shapes as per customer requirements.

Low-Temperature Impact Test

While SUS310S is primarily known for its high-temperature performance, it also exhibits good low-temperature toughness. Low-temperature impact testing is conducted to ensure that the steel can withstand sudden changes in temperature without cracking or failure. The specific results of these tests will depend on the steel's microstructure and heat treatment history but are generally satisfactory for most low-temperature applications.

Main Application Scenarios

JIS G4305 SUS310S cold-rolled stainless steel plate finds widespread applications in various industries due to its exceptional corrosion resistance and high-temperature strength. Some of the key application scenarios include:

· Petrochemical Industry: For piping, tanks, and other equipment exposed to high-temperature and corrosive environments.

· Power Generation: In boilers, heat exchangers, and other components operating at high temperatures.
