Stainless Steel Grades
A central stainless steel grade library for buyers comparing 201, 304, 316, 430, duplex, 904L, and low-carbon grades.
Use this grade library to choose stainless steel by corrosion resistance, welding behavior, finish, magnetic response, and cost. It is designed for searches such as 304 stainless steel, 316 stainless steel, 201 stainless steel, 430 stainless steel, 304L stainless steel, 316L stainless steel, 2205 duplex stainless steel, and 904L stainless steel.
Choose by buyer path
Grade first
Use this path for searches such as 304 stainless steel, 316 stainless steel, 430 stainless steel, and duplex stainless steel.
Environment first
Use this path when the buyer mentions chloride, coastal exposure, food cleaning chemicals, welding, or high temperature.
Product form first
Connect grade decisions to sheet, plate, coil, pipe, strip, bar, wire, and mesh pages to move the buyer toward quotation.
Most useful grade pages
- 201 Stainless Steel for cost-sensitive indoor use.
- 304 Stainless Steel for general-purpose projects.
- 316 Stainless Steel for chloride and marine exposure.
- 430 Stainless Steel for decorative and appliance applications.
- 2205 Duplex Stainless Steel for higher strength and tougher corrosion conditions.
- 304L Stainless Steel and 316L Stainless Steel for welded assemblies.
- 904L Stainless Steel for aggressive chemical environments.
Fast decision path
- Start with 304 if the environment is general and cost matters.
- Move to 316 if chlorides, salt spray, or cleaning chemicals are part of the job.
- Use 304L or 316L when welding is important and low-carbon material is preferred.
- Use 430 when magnetic material and lower cost are acceptable.

Practical grade questions buyers ask
Use these technical notes when the buying decision depends on magnetic response, corrosion risk, welding, food equipment, medical wording, or marine exposure. Each article links back to product forms, comparison pages, and quotation details.
- Is 304 Stainless Steel Magnetic? Explains why annealed 304 is usually non-magnetic but cold-worked 304 sheet, wire, strip, or formed parts may show magnetism.
- Will 304 Stainless Steel Rust? Covers chloride, salt, cleaning chemicals, contamination, and when to upgrade from 304 to 316 or 316L.
- 316L Stainless Steel for Food, Medical, and Marine Use Clarifies low-carbon 316L, welded assemblies, corrosion margin, and quotation requirements.
