Work Smarter with Edcon Steel
Cutting & Machining: Grade 431 is tough, so use quality high-speed steel or carbide tools and proper cutting fluid when machining or drilling. Always wear appropriate PPE when cutting or grinding stainless bars.
Corrosion Protection: While 431 is corrosion-resistant, it is not completely rust-proof. so in harsh environments take extra precautions. For projects in coastal or chloride-rich environments, periodically rinse or clean to prevent salt buildup.
Storage & Handling: Store indoors or under cover to keep clean and dry. Avoid storing or handling directly with mild steel off-cuts or steel tools that could transfer iron particles.
Buying Tip: Save on cost and freight by only ordering what you need with our cut-to-size service.
Check with a Professional: Our advice is general in nature. Always confirm your specific steel sizes, load-bearing requirements and compliance needs with a qualified engineer or builder.
Common Uses and Sectors: Stainless Steel 431 Grade
Stainless Steel 431 is a high-strength, heat-treatable martensitic stainless steel with excellent toughness and moderate corrosion resistance. It’s ideal for parts requiring both strength and resistance to wear, making it a popular choice for shafts, bolts, and marine hardware. With added nickel, it offers better corrosion performance than other 400-series steels while remaining magnetic and hardenable.
At Edcon Steel, we source and supply 431 in round, flat, and hex bar profiles to suit machining, fabrication, and structural applications. Whether you’re a builder needing high-strength components or a DIY user crafting durable parts, 431 is a versatile solution. All profiles are available in full lengths or can be cut to size for your project.
