Heat treatment 51CrV4 spring steel strip
Guangzhou Cgood Steel Co., Ltd is a professional manufacturer, supplying high quality heat treatment 51CrV4 spring steel strip. 51CrV4 spring steel has good mechanical properties with high hardenability. Adding vanadium (V) refines the grain of steel, it reduces overheat sensitivity and improves strength and toughness. 51CrV4 steel heat treatment has high fatigue strength and a high yield ratio.
Generally speaking, the chemical composition of 51CrV4 steel should meet the following requirements:
51CrV4 steel composition
Carbon: 0.47%-0.55%,
Silicon: max 0.40%,
Manganese: 0.70-1.10%
Phosphorus: max 0.035%
Sulfur: max 0.0035%
Chromium: 0.90%-1.20%
Nickel: max 0.25%.
51CrV4 carbon steel properties: strength, elasticity, fatigue resistance, hardenability.
