MANUFACTURING TECHNIQUE
General spring steels are produced in electric furnace, open hearth furnace, oxygen converter,and high quality spring steel of higher quality or special performance can be made in electro slag furnace or vacuum furnace.
PROCESSING PROPERTY
Spring Steel is commonly used in the condition of impact, vibration, or long-term stress. which makes the spring steel require higher tensile strength, limit of elasticity, fatigue strength. also requirement of definite hardenability, good surface quality, not easy decarburization.
PRODUCT FORMS AVAILABLE
Round bar (Diameter): 5.5mm to 450mm
Square bar / Flat bar: 3mm to 500mm
Heavy/middle plate via hot rolled: T60 - 400mm X W60 - 1000mm X L1000-12000mm
Sheet steel via cold rolled: T0.5 - 6mm X W100 - 1000mm X L1000 - 2000mm
Steel strip via cold rolled: T0.1 - 3mm X W5 - 200mm X L (or in coil form)
Forging piece: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
Reduction of area, ф ≥ (％): 30.0
