75Cr1 High Carbon Spring Steel

Introduction

75Cr1 is a high carbon steel with a carbon content between 0.74% and 0.80%. The addition of chromium facilitates the heat treatment process and allows higher hardness to be achieved than the standard C75 Carbon Steel.

75Cr1 carbon steel is a variation on En10132 C75, and US specification 1075. It is a high carbon steel strip grade supplied in either hardened and tempered or annealed condition.

75Cr1 carbon steel can be cut by laser or waterjet. It is generally used in manufacturing knives, springs, doctor blades, clutch plates, agricultural tools, and shims. Whilst it can and is used for a variety of spring and tool applications, it has found particular popularity in the manufacture of saws.

fushun stock 75Cr1 carbon steel from 1mm through to 5mm in the hardened and tempered condition and up to 10mm in the annealed condition.

75Cr1 High Carbon Spring Steel Strip

Spring steel strip normally contains between 0.40% to 0.80% carbon, with alloy elements added for the higher integrity products such as automotive clutches etc. Spring steels are quite used in the production of springs, also used in a number of applications where hardness or resistance to bending is required, such as lock parts or tools.

Spring steels are supplied in either annealed condition or hardened and tempered condition. Steel supplied in the annealed condition is usually hardened after the stamping and forming operation in component form. Hardened and tempered strip is more suitable for flat components or where the production is primarily laser cutting or plain blanking.

75Cr1 is a high carbon steel with carbon between 0.70% to 0.80%. The addition of chromium facilitates the heat treatment process and allows higher hardness to be achieved than the standard C75 carbon steel.

Our stable quality and superior technique are the foundations of our success, and we pride ourselves on delivering products that meet or exceed our customers' expectations. With a focus on innovation and efficiency, we utilize the latest technologies to ensure consistent quality and timely delivery.

We have more than 400 employees and our plant covers an area of nearly 15,000 square meters, with an annual output of 100,000 tons. Our advanced equipment allows us to produce high-quality spring steel products efficiently, meeting the needs of our customers.

In the production of spring steel wire, a variety of specialized equipment is essential. Shot Peening Machine. Wire Drawing Machine. Phosphating Equipment. Annealing Furnace. Polishing Equipment. Wire Coiling Machine. End Grinding Machine. Tensile and Compression Testing Machine.

Our commitment to excellence and reliability has resulted in long-standing partnerships with some of the biggest names in the industry. Like MW Industries, NHK Spring, Scherdel, Sogefi, Mubea etc. We also have established partnerships with several prominent Chinese steel groups, like Baowusteel, Xinyusteel, Nanjinsteel, Shagang etc.

Our spring steel wire comes in various categories such as music wire, hard drawn wire, oil tempered wire, chrome silicon wire, chrome vanadium wire, stainless steel wire, nickel plated wire, phosphate coated wire, galvanized wire, and copper coated wire.

Spring steel wire is a versatile material that is utilized in the manufacture of a wide array of products. including automotive suspension springs, valve springs, and torsion springs. Beyond springs, paper clips and mattress supports. In addition, spring steel wire is essential in the creation of retaining rings and circlips that are utilized to secure components on shafts or within bores, and in making various types of fasteners. The durability and resilience of spring steel wire also make it a key material in the manufacturing of certain types of cable, fencing, and even some musical instruments, such as piano and guitar strings, where its ability to return to its original shape after deformation is highly valued.
