Stainless Steel Hot Rolled Plate

Stainless steel hot rolled plates are available in a wide range of grades, including austenitic, ferritic, martensitic, duplex, and high-alloy stainless steels. The most commonly used grades are 304, 316L, 430, 410, 420, and 2205, depending on corrosion resistance, strength, and application requirements. Hot rolled plates are widely used in industrial and structural fields where strength and durability are more important than surface finish precision.

Description

Stainless steel hot rolled plate is produced by rolling stainless steel at high temperatures above the recrystallization point. This process allows the material to be formed in thicker dimensions and provides good mechanical strength, making it widely used in structural, industrial, and heavy-duty applications.

Compared with cold rolled sheets, hot rolled stainless steel plates are typically thicker, have a slightly rougher surface finish, and are more suitable for fabrication and engineering use.

Common Grades of Stainless Steel Hot Rolled Plate

Stainless steel hot rolled plates are available in a wide range of grades depending on corrosion resistance, strength, and application requirements.

1. Austenitic Stainless Steel Grades

These are the most widely used stainless steels due to excellent corrosion resistance and formability.

Grade	Key Characteristics	Typical Applications
201	Lower nickel, cost-effective, moderate corrosion resistance	Structural parts, decorative use
304 / 304L	Excellent corrosion resistance, versatile	Food equipment, chemical tanks, construction
316 / 316L	Improved chloride resistance with molybdenum	Marine, chemical, offshore equipment
321	Titanium-stabilized, good high-temperature resistance	Heat exchangers, exhaust systems

2. Ferritic Stainless Steel Grades

Ferritic grades provide good corrosion resistance and are magnetic.

Grade	Key Characteristics	Typical Applications
430	Good corrosion resistance, low cost	Decorative panels, appliances
409	Heat resistant, automotive grade	Exhaust systems
439	Improved weldability and corrosion resistance	Heat exchangers, automotive parts

3. Martensitic Stainless Steel Grades

These grades are heat-treatable and known for strength and hardness.

Grade	Key Characteristics	Typical Applications
410	Basic hardenable stainless steel	Mechanical parts, shafts
420	High hardness and wear resistance	Cutting tools, blades
431	High strength and improved corrosion resistance	Marine shafts, pump parts
440C	Very high hardness and wear resistance	Bearings, precision tools

4. Duplex Stainless Steel Grades

Duplex stainless steels combine high strength and excellent corrosion resistance.

Grade	Key Characteristics	Typical Applications
2205	Balanced strength and corrosion resistance	Chemical tanks, offshore platforms
2507	Super duplex, very high corrosion resistance	Seawater systems, oil & gas

5. High-Alloy / Special Stainless Grades

These are used in extreme environments requiring superior corrosion resistance.

Grade	Key Characteristics	Typical Applications
904L	High nickel and molybdenum content	Strong acid environments
254 SMO	Excellent pitting resistance	Seawater systems, desalination
1.4529 / Alloy 926	High corrosion resistance in harsh chemicals	Chemical processing
