Type 410 is the basic chromium grade of stainless steel. It combines excellent corrosion resistance with the ability to develop hardness and mechanical properties by conventional heat treating methods that are similar to those of Type 4130 Alloy Steel. It is magnetic in all conditions.

Applications: This grade is used for applications requiring good mechanical properties and involving corrosive conditions that are not too severe, such as valve parts, cutlery, good industry machine parts, screws, bolts, pump rods and pistons, etc. In the annealed condition, it may be drawn or formed. In the aircraft industry Type 410 is used for parts such as compressor shrouds, where oxidation resistance is required up to 1OO0 Deg. F. Useful at higher temperatures only when stresses are low.

Corrosion Resistance: Excellent resistance to corrosion from the atmosphere, fresh water, iron bearing mine waters, food acids, neutral and basic salts, mild acids and alkalis. This grade has excellent corrosion resistance in all conditions of heat treatment, but maximum resistance is obtained by hardening and polishing. In general, corrosive resistance qualities are only slightly less than those of Type 430.

Resistance To Scaling: Resists scaling at temperatures up. to approximately 1200-1300 Deg.F in continuous service. Over 1300 Deg. F it has relatively low strength, and resistance to oxidation is reduced.

Hardenability: specification AMS-5504C requires that material 3/8" thick and under, and 3/8" specimens from heavier material, shall be capable of attaining hardness of Rockwell 'C' 35-45 after being heated to 1740-1760 Deg. F held at heat for 15-30 minutes, and cooled in still air.

Machinability: Type 410 has better machining characteristics than the chromium-nickel grades. It has a machinability rating of 54%, with B-1112 rated 100%. Surface cutting speed on automatic screw machines is approximately 90 feet per minute.

Weldability: May be welded by all the commercial processes except forge or hammer welding. Large sections should be preheated prior to welding. Because of its air hardening properties, annealing after welding is recommended to obtain maximum ductility and toughness.

Forming: This grade has fair forming and stamping properties. Forging: Forge between 2000 and 2200 Deg. F Do not forge below 1650 Deg. F. Cool slowly.

Annealing: Full annealing range is between 1550 and 1650 Deg. F. Cool slowly in furnace. Low annealing range is between 1200 and 1400 Deg. F. Cool in air.

Hardening: Hardening range is between 1750 and 1850 Deg. F Quench large sections in oil. Small sections may be quenched in air. Temper to required hardness.
