Cr (%): -
Cu + 10Sn ≤0.60
MECHANICAL PROPERTIES
Condition: Quenched and tempered
Mechanical property ≥|σs/MPa: 1450~1750
Mechanical property ≥|σb/MPa: 1300
Mechanical property ≥|δ5(%): 6
Hardness after soft annealing ≤HBW: 248
HEAT TREATMENT
Spring steel requires higher strength and fatigue limit, usage in the condition of quenching + mesothermal tempering, then it can get higher elastic limit. Process engineering of heat treatment is very important to inherent quality of spring steel.
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. Spring steel should possess excellent combination property, such as mechanical property (limit of elasticity, ultimate strength, yield ratio), relaxation resistant, fatigue property, hardenability, physical and chemical property (heat resistance,low temperature resistant, antioxidation, corrosion resistance). To meet the above performance requirement, Spring steel has fine metallurgical quality ( high purity, homogeneity), excellent surface quality ( specially on surface defect and decarburization), precise external form and dimensions.
PRODUCT PROFILE
Round bar / Wire rod (Diameter): 0.50mm to 800mm
Square bar / Flat bar: 3mm to 800mm
