SAE 1075, CK75 and C75 are all grades of spring steel strips with same properties. They are typically used in the manufacturing of springs, saw blades, and other application requiring high strength and resilience. SAE 1075 CK75 C75 is a carbon steel grade that contains carbon content between 0.70-0.80%. These spring steel strips have good elastic limit, high tensile strength, and good wear resistance. They are also resistant to deformation and fatigue, can be heat treated to acheive specific properties, such as increased hardness or improved toughness. Spring steel strips are typically supplied in a hardened and tempered condition and annealed condtions, wiht thickness ranging from 0.10mm to 6.00mm and width from 2.00mm to 500mm. They are available in various finishes, including nature, bright, blue tempered, yellow tempered and white tempered.

In our production, our facilities allow max 2.5mm thickness andmax  260mm width. We are the best heat - treating steel supplier in China, material,hardness, surface,size, can be made according to your request. Welcome to contact us at any time for any enquiry.

C67s spring steel strip is a standard material with no corrosion resistance, equivalent to CK67, SAE1070. After hardened and tempered condition, it is widely used in rolling shutter door spring, saw blade, plaster trowel, scraper, putty knives, shoe insole, spring washer, etc. Under tempered condition, Blue, bright, yellow, black, surfaces are available by adjusting the temperature and times in the furnace.

c75s spring steel is a low alloy, carbon steel material with carbon content  0.72-0.84. This material can be heat-treated to the required tensile strength, operated by annealing process (CRCA) or hardened and tempered condition (Q+T). 

Guangzhou Cgoodsteel Co.,Ltd  makes hardened and tempered medium & high carbon steel strips which has excellent spring properties, unfirm hardnedd and texture, suitable for extensive applications. Quality is confirming to National standard (GB) and internation standard (DIN,ASTM etc.)

we supply good quality carbon spring steel coils with these equivalent materials:c50s-ck50-sae1050-c50,c60s-ck60-sae1060-c60,c70s-ck67-sae1070-c67,c75s-ck75-sae1075-c80

51CrV4 is chromium vanadium type spring steel with low distortion properties and easily heat treated, suitable for oil hardneing and tempering. Hardened and tempered 51CrV4 steel (equivalent to AISI6150 steel), offers excellent toughness and shock resistance which makes it suitable alloy spring steel parts exposed to stress, vibration, shock. This material is widely use for making band saw blade.

50CrV4 spring steel is supplied in strip/coil/sheet conditions. When treating the steel in hardening and tempering conditions, it give steel spring characteristics with excellent resistance.

Flat spring steel has the property of high yield strengths, resistance to deformation with ability to return to its original shape. GuangWei YouLiang produces spring steel strips in anneal treatment and hardened & tempered treatment. Annealed spring steel strips allows to be formed prior to the heat treatment

75Cr1 is one type of high carbon steel grade, which our factory supplies in quenched and tempered conditions or cold rolled annealed steel. C75Cr1 steel is widely used for kinds of springs and tool application, especially in the manufacture of saws. 

We produce thousand tons wide range of spring steel strips (C67S C70S C75S SAE 1075 C80 C95S steel grades) in cold rolled annealed and hardened & tempered conditions, built on rich experience in the steel industry. The elasticity of spring steel strips have great influence on the functionality of end-use products with highly load demand.
