The Properties and Types of Spring Steel

Properties of Spring Steel

• High Elasticity
• High Strength
• High Fatigue Resistance
• Good Resistance to Wear
• Good Corrosion Resistance

Types of Spring Steel

1.High Carbon Spring Steel

High-carbon spring steel possess varying percentages of carbon, with higher carbon content resulting in greater strength and hardness.

AISI 1050, 1070, 1074, and 1095 are the most commonly used grades of high-carbon spring steel.

AISI 1095 possess the greatest strength and hardness.

2.Alloy Spring Steel

AISI 5160, 6150, and 9254 are the most commonly used grades of alloy spring steel.

3.Stainless Spring Steel

AISI 301, 304, and 316 are the most commonly used stainless spring steel grades in the industry.

These grades offer high wear and corrosion resistance, with enhanced strength, and toughness.

AISI 301 and 304 have a higher yield strength but lower wear resistance than AISI 316 due to the presence of molybdenum.

4.Nickel Alloy Spring Steel

Inconel 718 and 625 are common grades of nickel alloy spring steel that are used in the metalworking industry.

5.Copper Alloy Spring Steel

Beryllium copper and phosphor bronze are the most popular grades in use.

Beryllium copper has a much higher fatigue strength, but phosphor bronze has higher conductivity, making it ideal for conducting applications.

6.Chrome-Silicon Spring Steel

AISI 9260 and 9254 are broadly used popular grades, with AISI 9260 possessing a higher percentage of silicon.
