It is preferred that welding be carried out on while in the annealed condition, and that the work piece, immediately on cooling to hand warm, is then stress relieved at o C – o C prior to hardening and tempering.


Please refer to the relevant standards for important work. Sections available black round, black square, bright round and black flat. Generally machined components and pipe fittings.

It offers high resistance to corrosion.

Do not forge below o C. Or are we already there? Supplied heat treated with a high tensile strength. Lower Carbon grades S15 and less have improved weldability. This grade is almost as popular as the grade the increased Mo content makes the steel more suitable for resisting pitting and crevice then Grade. Used for gears, and 871m40 strength shafts etc.

If so then feel free to register using the link ‘here’. The tensile strength of the core is usually not affected since the nitriding temperature range b970 generally below the original tempering temperature employed. Following quenching to hand warm, most components should be tempered between o C – o C to remove quenching stresses in the case. Low Strength but good ductility. Supplied as black round or square bar bs97 bright round or square, and hexagons.
