What types of S316 are available?

316 (Standard Grade) The basic version of Type 316 stainless steel. Composition: ~16–18% Cr, 10–14% Ni, 2–3% Mo. Properties: Excellent corrosion and oxidation resistance, good formability and weldability. Uses: Marine parts, chemical processing equipment, and food-grade applications. 2. 316L (Low Carbon) The “L” stands for Low Carbon (≤0.03% C). Advantage: Lower carbon content reduces carbide precipitation during welding, improving corrosion resistance in welded structures . Uses: Pressure vessels, pharmaceutical equipment, and marine components that require extensive welding. 3. 316H (High Carbon) The “H” stands for High Carbon (0.04–0.10% C). Advantage: Higher carbon increases strength and creep resistance at elevated temperatures. Uses: High-temperature industrial applications like heat exchangers, boilers, and furnace parts.

What types of S410 are available?

410 (Standard Grade) Base composition: ~11.5–13.5% Cr, 0.08–0.15% C. Features: General-purpose martensitic stainless steel with good strength, hardness, and moderate corrosion resistance . Uses: Cutlery, pump shafts, turbine blades, valve components, and fasteners. 2. 410S (Low Carbon Variant) Lower carbon content (≤0.08%) than standard 410. Improved weldability and toughness , but cannot be hardened by heat treatment as effectively. Better resistance to scaling and oxidation at high temperatures. Uses: Welded or formed parts, exhaust systems, and furnace components. 3. 410HT (Heat-Treated 410) Same chemical composition as standard 410 but supplied in a hardened and tempered condition. Offers high strength and wear resistance for ready-to-use mechanical parts.

S316/S410 Machining FAQs

S316 stainless steel (commonly known as Type 316 stainless steel) is an austenitic chromium-nickel stainless steel that contains molybdenum for enhanced corrosion resistance. It is one of the most widely used stainless steels for harsh or corrosive environments.

S410 stainless steel (commonly known as Type 410 stainless steel) is a martensitic stainless steel that offers a strong combination of high strength, hardness, and moderate corrosion resistance. It’s one of the earliest and most widely used martensitic grades, often chosen when mechanical strength and wear resistance are more important than maximum corrosion resistance.
