Description
Cambiar por la correcta bar is one of the most common types of cold finished steel bar, since it is a versatile steel grade that can be used in hundreds of different applications. 1018 CD steel is a low carbon steel and medium manganese content that is an ideal choice for applications that do not need the strength of the highest carbon steel grades, including carbureted components. The 1018 steel bar has excellent weldability properties, is good for cold forming/bending applications and has good machinability as well as surface hardening properties.
Application
We supply 1018 cold finished steel bars to a variety of industries such as automotive, heavy machinery, material handling, electric motors and many more. Some common components can be bushings, stabilizer bars, suspensions, fasteners, connecting rods, bolts, spacers, gears, among others.

Description
Grade 1045 is characterized by good weldability, good machinability and high strength and impact properties, whether in hot rolling or cold finishing conditions.
1045 is widely used by all sectors of the industry for applications that require more hardness and wear resistance than soft, low carbon steels.
Application
Some components of grade 1045 include shafts, pistons, heavy duty machinery parts, pump shafts (psq), pinions, rollers, hydraulic cylinders, axles, among others.

Description
Grade 4140 steel is a low alloy steel that contains chromium, molybdenum and manganese to improve its mechanical properties. It is widely used in numerous industries and is an excellent choice of material due to its hardness, high resistance to fatigue and resistance to abrasion and impact. Not many grades can match the versatility and utility of 4140.
Application
Common applications include drill collars, piston pins, shafts, pinions, gears, crankshafts, spindles and couplings.
