Heat Treatment
Annealing - Grade 410 steels can be fully annealed at temperatures from 815 to 900°C, followed by slow furnace cooling and air-cooling. Process annealing of grade 410 steels can be carried out at temperatures ranging from 650 to 760°C and air-cooled.
Hardening - Hardening of grade 410 steels can be performed at 925 to 1010°C, followed by air and oil quenching. Heavy sections of grade 410 need to be oil quenched. Tempering, to enhance the mechanical properties and hardness of grade 410 steels, follows this process. It is not recommended to perform tempering at temperatures from 400 to 580°C.
Welding
Grade 410 steels can be welded using all conventional welding techniques, but the materials should pre-heated at 150 to 260°C followed by post-weld annealing treatment, to mitigate cracking. Grade 410 welding rods are recommended for tempering and post-hardening. In the "as welded" conditions, grade 309 filler rods can be used to achieve a ductile joint.
According to AS 1554.6 standards, grade 309 electrodes or rods are preferred for welding 410 steels.
Machining
Grade 410 steels can be easily machined in highly tempered or annealed conditions. However, it is hard to machine grade 410 steels if they are hardened above 30HRC. Free machining grade 416 is the best alternative.
Applications
Grade 410 stainless steels find applications in the following:
· Bolts, screws, bushings and nuts
· Petroleum fractionating structures
· Shafts, pumps and valves
· Mine ladder rungs
· Gas turbines
Introduction
Grade 410 stainless steels are general-purpose martensitic stainless steels containing 11.5% chromium, which provide good corrosion resistance properties. However, the corrosion resistance of grade 410 steels can be further enhanced by a series of processes such as hardening, tempering and polishing. Quenching and tempering can harden grade 410 steels. They are generally used for applications involving mild corrosion, heat resistance and high strength.
Martensitic stainless steels are fabricated using techniques that require final heat treatment. These grades are less resistant to corrosion when compared to that of austenitic grades. Their operating temperatures are often affected by their loss of strength at high temperatures, due to over-tempering and loss of ductility at sub-zero temperatures.
