Advantages of JIS Alloy Steel Plate
Superior strength-to-weight ratio: By incorporating alloying elements, plates achieve higher strength without excessive thickness. This results in lighter components that still deliver robust performance.
Enhanced wear and abrasion resistance: Plates used in mining, crushers, and construction benefit from the toughness and longevity that alloy steels offer—especially when combined with surface hardening.
High thermal and pressure tolerance: Applications in boilers, refineries, and reactors demand materials that don’t degrade under high pressure or heat—this is where alloy steel plate thrives.
Corrosion resistance: Especially with chromium or nickel-enhanced alloys, these plates hold up against harsh chemicals, salty air, and moisture.
Long-term durability: Fewer replacements, less downtime, and better roi over time make alloy steel plate a cost-effective option—even with higher initial investment.

Steel structural is defined material standard for hot rolled steel plates, sheets, and strips for general structural usage. Primarily employed in the motors parts industry because of its low carbon content & lowest limit of tensile strength at 400 mpa.
This steel grade exhibits good weldability and machinability, allowing for ease in fabrication and assembly in various structural projects. While it has modest corrosion resistance, it is often coated or painted to enhance its durability in corrosive environments.
Application of JIS Alloy Steel Plate
Construction and infrastructure: Used in the construction of buildings, bridges, and tunnels, where strength and durability are paramount.
Automotive and aerospace: Critical in the manufacturing of vehicles and aircraft, alloy steel plates contribute to safety, performance, and fuel efficiency.
Energy production: In the energy sector, including oil, gas, and renewable energies, these plates are used in the construction of pressure vessels, pipelines, and other equipment.
Defence: Alloy steel plates are employed in the manufacture of military vehicles and structural components, offering protection and reliability in demanding conditions.
Production Process of JIS Alloy Steel Plate
Selection of raw materials: Select high-quality raw materials that meet the requirements of standard to ensure product quality.
Melting: Use electric arc furnace or other furnace type for melting, control alloy composition and gas content, and ensure that the chemical composition of steel meets the standard.
Continuous casting: Obtain uniform slab through continuous casting process to ensure the smooth progress of subsequent rolling process.
Hot rolling: Using high temperature rolling process, the slab is rolled into steel plate that meets the specifications, and the rolling temperature and deformation are controlled.
Surface treatment: According to the needs of the steel plate cleaning, oil removal, shot blasting and other surface treatment process, to prepare for subsequent processing and application.
