AISI 1075 Ck75 C75S 1.1248 Spring Steel

AISI 1075 Spring Steel

AISI 1075 Carbon Steel (UNS G10750)

AISI 1075 Carbon Steel (UNS G10750)

Introduction

Carbon steels contain carbon as the chief alloying element. Residual elements such as copper, chromium, molybdenum, nickel, and aluminium are also present in traces. They also contain 1.2% of manganese and 0.4% of silicon. AISI 1075 carbon steel is more brittle than the lower carbon steels.

Fabrication and Heat Treatment

Machinability

The machinability rate of AISI 1075 carbon steel is 50.

Forming

AISI 1075 carbon steel can be formed using conventional techniques.

Welding

AISI 1075 carbon steel can be welded using all welding methods. It is pre-heated at 260 to 315°C (500 to 600°F) and post-heated at 649 to 788°C (1200 to 1450°F) to prevent cracking.

Heat Treatment

AISI 1075 carbon steel can be hardened at 899°C (1650°F). It is then quenched in oil followed by tempering.

Forging

AISI 1075 carbon steel can be forged at 927 to 1204°C (1700 to 2200°F) followed by annealing.

Hot Working

AISI 1075 carbon steel can be hot worked at 94 to 483°C (200 to 900°F).

Cold Working

Cold working of AISI 1075 carbon steel is performed using conventional methods in the annealed condition. It needs more force compared to low carbon steels to perform this process.

Annealing

Annealing of AISI 1075 carbon steel can be done at 926°C (1700°F) followed by slowly cooling in the furnace.

Tempering

AISI 1075 carbon steel is tempered at 371 to 705°C (700 to 1300°F) after heating and quenching. It is usually used in the hardened condition of Rockwell C 55.

Hardening

AISI 1075 carbon steel is hardened by cold working, heating, and quenching.

 

Applications

AISI 1075 carbon steel is mainly used in cutting tools, and springs. Both metals are used to create many of the same products. The decision of which type to use in manufacturing depends upon your manufacturing process and the unique properties you would like the final product to have. Both 1075 and 1095 spring steel are used to make:

Vehicle Coil Springs

Spring Clamps

Antennas

S-Tines

Lock Picks

Clock Hands

 

STANDARD SPECIFICATIONS: ASTM A684-17

TYPICAL ANALYSIS: C .69/.80 Mn .40/.80 P .020 max. S .025 max Si.15/.30

TYPICAL HARDNESS:   Cold Rolled, Spherically annealed, RB 85

TYPICAL APPLICATIONS: Blades, brackets, clutches, hand tools, springs, scrapers, washers, & wear strips

 

XC75 steel is perfect for beginners starting to make knives.

The XC 75 carbon steel is also called 1075 in the USA and is the ideal grade to use for beginners. It provides excellent value for money and creates good quality blades at a very reasonable price.

 

Ideal for forging Damascus blades.

The XC75 steel has little or no alloy, and is very easy to weld. Combined with 15N20, which has the same carbon content – or may contain pure nickel for a more brilliant white finish – it can be used to obtain very attractive patterns  whilst conserving very good cutting properties
