At temperatures ranging from 390 F (200 C) to 480 F (250 C),the zinc-iron alloy layers will continue to protect the steel from corrosion.High temperatures above 480 F (250 C) will accelerate peeling and continued exposure can result in the zinc-iron alloy layers cracking and separating from the steel.How heat treating and annealing stainless steel impacts Ferritic stainless steels cannot be hardened by heat treatment.However,they display maximum ductility,impact toughness and corrosion resistance; theyre also cheap and are very resistant to scaling at high temperatures (such as in exhaust systems).High temperature steel - MolybdenumMolybdenum in solid solution reduces the creep rate of steel very effectively.It slows the coagulation and coarsening (Ostwald ripening) of carbides during high-temperature service.The best results in terms of elevated-temperature strength are obtained by quenching and tempering to produce a microstructure consisting of upper bainite.

High Carbon Steels : Total Materia Article

Generally,the high carbon steels contain from 0.60 to 1.00% C with manganese contents ranging from 0.30 to 0.90%.The pearlite has a very fine structure,which makes the steel very hard.Unfortunately this also makes the steel quite brittle and much less ductile than mild steel.Heat Treatment- Annealing,Normalizing,Hardening This heat treatment process carried out for steel parts which have been already hardened,in order to reduce bitterness and unequal stress develop as a result of hardening.This process reduces brittleness and hardness but improves the tensile strength of Steel.It increases the toughness of Steel at the expenses of loss of some hardness.Heat Treatment- Annealing,Normalizing,Hardening Heat treatment involves heating of metal in the solid-state and then subsequently cooled at varied cooling rates.It is very important manufacturing process that can not only help the manufacturing process but can also improve the product,its performance,and its characteristics in many ways.
