410 is basic martensitic stainless steel bright bar.

Core feature: Hardenable by quenching for high hardness and wear resistance. Annealed grade has moderate plasticity for simple bending & stamping; cold working causes rapid work hardening, toughness restored after tempering.

Its corrosion resistance is slightly better than carbon steel, only resistant to dry atmosphere, fresh water and neutral weak acid, poor against chloride and seawater. Long-term service at 400~600℃ precipitates chromium carbide and leads to welding sensitization, post-weld full heat treatment is mandatory to recover corrosion resistance and toughness.

Hot forming window 800~1000℃; overheating causes coarse grain embrittlement. Supports simple cold forming; stable machinability in annealed condition, high tool wear for quenched hard material.

Chemical element content (%)

Specification：1.00~300.00mm

Application:It is mainly used to manufacture general small valve spools, fresh water pump shafts, medium-temperature dry boiler fasteners, load-bearing tool bars for heat treatment furnaces, wear-resistant pins for food drying equipment, chloride-free dry heat petrochemical fittings, hot air circulation valve bodies, general wear-resistant stainless steel standard parts, short transmission shafts for small machinery, connectors for indoor dry equipment, etc.
Widely applied in general valve industry, fresh water circulating facilities, thermal power boiler low-temperature auxiliary parts, industrial heat treatment furnaces, food drying lines, petrochemical dry heat units, civil hot air drying equipment and general small machinery wear-resistant component industries.

Core Advantages Over Competitors

1. High quality stability: Full closed-loop production & online spectral inspection strictly control C & Cr ratio with uniform controllable martensitic grain structure, stable hardness range after quenching for consistent mass production of wear-resistant valves and pump shafts.

2. Excellent surface quality: High-precision cold drawing & centerless grinding bars free of scale, scratches and pits with smooth finish. Good surface after turning in soft annealed condition, no secondary polishing required for simple parts.

3. Ultra-high dimensional accuracy: Precision cold rolling mills & automatic online detectors narrow tolerance with tiny single-bar deviation and high batch uniformity, unifying part sizes during automatic mass production to raise finished yield.

4. Rich product variety: According to market demand and customer's special requirements, customized products are provided to meet the use requirements under various complex working conditions, providing customers with more choices.

5. Perfect after-sales service: The perfect after-sales service system can respond to customer needs and feedback in a timely manner. For problems encountered by customers during use, technical support and solutions are provided to customers quickly.
