ASTM 316L 304L stainless steel forging flange,Alloy Steel Forgings
The stainless steel flange materials for 316L. It’s used in petroleum pipe link, outside diameter 2300mm, inner diameter 1900mm, height 80mm, weight 830kg (roughing). The material advantage is follow.
1. This material has strong corrosion resistance and high strength, it’s can working to bad environment and doesn’t corrosion, variant, fracture, oxidation, etc.
2. Stainless steel flange life will be higher than that of other alloy steel or carbon steel manufacturing flange. So save repair and cost.
3. Stainless steel after forging after solid solution treatment, the comprehensive mechanical performance is good. The required performance value is ok of the tensile, yield and impact.
|Description||It is widely used in petroleum , chemical, nuclear power , construction, shipbuilding and other industries , with strong corrosion resistance and good performance|
|Smelting Process:||EF+LF + VD|
|Process||Ingot→heat → forging → Heat treatment (Normalizing+ tempering) → Inspection →rough
→UT →2nd Heat treatment →finishing machining →Inspection
|UT standard||ASTM A388 or EN10228|
Forging process flow quality control:
Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment
