Hardened & Tempered Steel Strips

ZENHARD, Walzen make Hardened & Tempered Medium & High Carbon Steel Strips, finds wide applications in special industrial uses. ZENHARD has excellent spring properties, uniform hardness and texture, ZENHARD has precision blanking ability and rationalizes further processing by eliminating post heat treatment & distortion and thereby increases productivity.

Walzen Strips Pvt. Ltd. manufactures ZENHARD, Hardened & Tempered Steel Strips, conforming to National and International Standards viz, IS: 2507, DIN 17222. BS: 1449, ASTM A-682 Medium & High Carbon and Low Alloy steel strips, cold rolled in-house, are heat-treated in continuous line to develop high hardness, toughness, tensile and spring properties.
Steps involved for manufacture of Hardened & Tempered Steel strips:

Hardening & Tempering:
Austenitizing of Medium & High Carbon and Low Alloy steels is carried out in 12 M long gas fired furnace with automatic controls and heat resistant S.S. Muffle to provide inert cover to the strips. Quenchingl in oil produces very hard martensite, which is then tempered down in a 7 M long electrically heated tempering furnace. Variable speed DC drive with UPS back-up ensures uninterrupted processing even during power failure.

Edge Rounding:
Rounding of one or both edges is essential for certain applications requiring high fatigue life. This is done by machining of edges with profiled carbide tips.

Grinding:
During hardening and tempering the strip surface gets oxidized, developing a Blue-grey finish. But in many application the strips are required in Bright finish. This is obtained by grinding the surfaces with waterproof-coated abrasive belts in a grinding machine with coolant flow.

Suppliers of round bar we can offer diameters in EN47 sawn to your required lengths as 1 offs or multiple cut pieces. Ground steel bar can be supplied, providing a high quality precision ground spring steel bar to tight tolerances.       

Applications:

• EN47 is used widely in the motor vehicle industry and many general engineering applications. Suitable for applications that require high tensile strength and toughness. Typical applications include crankshafts, steering knuckles, gears, spindles and pumps.

Forging:  

• Preheat the steel carefully, then raise temperature to 1050°C for forging. Do not forge below 840°C. After forging EN47 spring steel cool slowly, preferably in a furnace.

Annealing:  

• Heat slowly to 820-840°C, soak well. Cool slowly in the furnace.

Hardening:   

• Heat slowly to 650-700°C and thoroughly soak. Continue to heat the steel to the final hardening temperature of 830-860°C and allow the component to be heated through. Quench in oil.

Tempering   

• Temper the EN47 spring steel component immediately after quenching whilst tools are still hand warm. Re-heat to the tempering temperature then soak for one hour per 25 millimetre of total thickness (2 hours minimum) Cool in air. For most applications tempering of this grade will be between 400-600°C.

Heat Treatment   

• Heat treatment temperatures, including rate of heating, cooling and soaking times etc. will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of EN47.

Product Details:

High carbon steels contain from 0.7 to 1.00% C with manganese ranging from 0.5% to 0.9% This steels are commonly known as spring steel. These steels are generally operated at very high stresses and heat-treated to obtain the maximum elastic limits and fatigue resistance without becoming sufficiently brittle to cause sudden failure in service. Hardenability of spring steel is very important because only fully hardened springs have the maximum resistance to take a permanent set (sagging)

We offer the following grades in spring steel:
C60, C65, C70, C75, C85, HC-14, En 42 J, C-98, C-100, C-124 / HC21 etc.
