GB/T 30CrMnSiA Alloy Round Steel Bars
Alloy structural steel is a kind of steel which is used as
mechanical parts and various engineering components,whichcontains
one or more alloy elements.
- 30CrMnSiA is a medium carbon with high strength and poor welding
performance.
- 30CrMnSiA has high strength and sufficient toughness after
quenching and tempering, and hardenability is also good. After
quenching and tempering, the material can be used as a grinding
wheel shaft, gears and sprockets.
- 30CrMnSiA has good processability, small processing deformation and
good fatigue resistance. For shaft and piston parts and so on. It
is used in various special wear parts such as automobiles and
airplanes.
- The material is darker in color and galvanized can add aesthetics
and rust.
- EAF+(ESR) or EAF+LF+VD+(ESR)
- HOT rolled; Cold rolled; Forged; Cold Drawn
- Heat Treatment: Untreated, Annealing, N+T, Q+T
- Smelting: EAF+LF+VD (+ESR)
- Surface Finish: Black, Rough Machined, Peeled, Turned or upon
request
- UT 100% passed
- Cutting service provided
- Third Party inspection is acceptable (SGS, BV etc.)
