Product Process

Boiler steel plate process

Forging	Forge by heating slowly and uniformly to 1000°C. After forging cool slowly in furnace or thermoinsulating material.
Annealing	Heat slowly to 780°C. Cool slowly in furnace at a slow rate to 600°C and then cool in air.
Stress Relieving	When heavy machining and/or grinding has been carried out, stress relieving is advisable to minimise the danger of distortion or cracking during the subsequent heat treatment. To stress relieve, heat the tools slowly to 650°C, soak for a minimum of two hours per 25mm of section and allow to cool down in the furnace to 500°C then continue to cool freely in air. The tools can then be finish machined, leaving on an allowance for final grinding after hardening and tempering.
Hardening	Pre heat the 600-700°C until heated through. Continue heating the to the final hardening temperature of 980-1050°C and allow the component to be heated through. Protect the component against decarburisation by using a neutral salt bath, controlled atmosphere furnace or vacuum. Air cool or quench in oil.
Tempering	Heat the 1.2083 uniformly and thoroughly to the selected tempering temperature and hold at heat for one hour per 25mm of total thickness. Double tempering is recommended. To achieve the best permutation of hardness, toughness and corrosion resistance it is recommended to temper at 250°C.
Heat Treatment	Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each s136 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of stainless tool steel.

Product Application

Applicate of different grade Boiler steel plate

1>.Q195,Q215
Because of low strength,good plasticity and toughness,easy to processing,so widely used in Building,structure,motorcycle bodywork steel nails,rivets,bolts and iron wire,etc.
2>.Q255, Q275
high strength, but plasticity,weldability and toughness is not very good, not easy to weld and cold bending processing, so they widely used for rolling reinforcing steel bar or bolt accessories, but more in the mechanical parts and tools, etc.
3>.Q235
Widely used in Building engineering. carbon content is 0.14% ~ 0.22%, with high strength, good plasticity and toughness and weldability, comprehensive performance is good,socan meet general steel structure and steel reinforced concrete requirements,and low cost..
So it also widely used to make reinforcing steel bar or building room frame, high-voltage transmission tower, Bridges, vehicles, boiler, containers, ship,
