Spring Steel Coil and Strip
High carbon and alloy coil for springs blades stamped parts and molds where the section has to spring back under load
Spring steel coil is the part of the steel coil range bought for elastic components rather than for structure. It covers spring steel coil and spring steel strip in the specialized alloy steel and carbon steel grades used to make springs and other elastic components together with 1075 C75 high carbon spring steel coil. The 1075 grade is a high carbon spring steel with high strength high hardness excellent ductility outstanding resilience and fatigue resistance and it is widely used in the manufacturing of springs blades stamped parts and molds. What separates usable coil from scrap on a press is metallurgical quality meaning high purity and uniformity good surface quality with strict control of surface defects and decarburization and precise shape and size.

What This Range Is For
Decarburized Surface Cutting Fatigue Life
A decarburized skin is softer than the core and that is where fatigue cracks start. Spring steel coil is bought with strict control of surface defects and decarburization for exactly that reason.
Coil Shape Wrong for the Press
Camber and thickness variation upset the feed and chew through tool life. Precise shape and size is part of what a spring steel coil is specified on and not a bonus.
Delivery Condition Left Unstated
Cold rolled annealed and quenched material behave differently at forming and at heat treatment. Naming the condition on the order keeps the wrong temper off your press.
Inclusions Appearing After Forming
High purity and uniformity in the metallurgical quality is what keeps inclusions out of a part that will be cycled for the life of the machine it sits in.
Full Width Coil Bought for Narrow Strip Work
decoiling to the width you actually feed removes the edge scrap and the cost of storing the remainder until the next order.
Who Buys It
Buyers Who Order From This Range
- Spring manufacturers buying coil and strip by grade temper and thickness
- Stamping shops feeding automatic presses from slit strip
- Blade and hand tool makers working in high carbon grades
- Mold and die shops needing spring sections for inserts and ejector components
- Vehicle and agricultural equipment part suppliers making clips and flat springs
- Service centers decoiling stock for regional spring and stamping workshops
Core Advantages
Why Source This Range From Tianyu Metal
High Carbon Grade With Stated Properties
1075 C75 is a high carbon spring steel with high strength high hardness excellent ductility outstanding resilience and fatigue resistance so the grade choice can be justified on the drawing.
Thickness From Strip to Heavy Section
Thickness runs from 0 to 20mm so thin flat spring strip and heavier leaf sections come out of the same range and the same supplier.
Three Delivery Conditions
Cold rolled annealed and quenched material is available so the coil arrives in the condition your forming and heat treatment route expects.
Alloy and Carbon Spring Grades
Spring steel coils cover specialized alloy steel coils and carbon steel coils for springs and other elastic components so the grade can follow the duty instead of the stock list.
Surface and Shape Held to Spec
Good surface quality with strict control of surface defects and decarburization plus precise shape and size keep the strip feeding and the part repeatable.
Coil or Slit Strip
The same material ships as spring steel coil or spring steel strip so the decoiling step can be done before the container is loaded.
Application Scenarios
Where This Range Ends Up
Compression and Tension Spring Making
Coiled and flat springs where resilience and fatigue resistance decide how many cycles the part survives in service.
Blade and Cutting Edge Production
Blades where high hardness and ductility have to coexist in one thin section without the edge chipping.
Press Stamped Elastic Parts
Clips retainers and spring washers stamped from strip where the part has to return to shape after every assembly cycle.
Mold and Die Components
Mold inserts and ejector parts made from high carbon spring steel where hardness after quenching is the reason the grade was chosen.
Vehicle and Machinery Flat Springs
Leaf and flat sections for machinery and vehicle assemblies that work under repeated load and vibration.
Buying Guide
What To State When You Order
Name the grade such as 1075 or C75 and say whether an alloy spring grade can be offered as an alternative
Give thickness inside the 0 to 20mm range together with the strip width you feed rather than a coil weight
State the delivery condition you need which is cold rolled annealed or quenched
Say what surface condition and decarburization control the part requires because fatigue life depends on it
Confirm the coil inner diameter and whether you want full width coil or slit strip
Ask for the mill test certificate and state the packing so coils arrive dry banded and liftable by your crane

Spring Steel Coil FAQ
What is 1075 C75 spring steel coil?
It is a high carbon spring steel with high strength high hardness excellent ductility outstanding resilience and fatigue resistance. It is widely used in the manufacturing of springs blades stamped parts and molds.
What thickness is available in spring steel coil?
Thickness runs from 0 to 20mm and the size itself is customized. Tell us the strip width you feed and we will confirm the decoiling before the coil is released.
Which delivery conditions can you supply?
Cold rolled annealed and quenched. Say which one suits your forming and heat treatment route so the coil does not have to be softened or hardened again at your end.
Why does decarburization matter on spring steel?
A decarburized surface layer is softer than the core and fatigue cracks begin there. Spring steel coil is supplied with strict control of surface defects and decarburization.
Is spring steel always a high carbon grade?
No. Spring steel coils cover specialized alloy steel coils and carbon steel coils used for springs and other elastic components. The grade follows the load the section and the cycle count.
Can you supply strip instead of full coil?
Yes. The range is listed as spring steel coil and spring steel strip so decoiling to your width is done before shipment and you receive material ready to feed.
