The Fabrication Process of Stainless Steel

Stainless steel is a versatile material used for a wide range of structures. The fabricating process will enhance the durability of the stainless steel so it can be maximized for long term use. Basically, there is a 3 step process in the fabrication of stainless steel, the welding, work hardening and machining. There is a process called custom fabrication in which the stainless steel is constructed via the requirements of a particular industry.

Work Hardening

Work hardening is done to further strengthen the steel. There may be deformations present in the steel and this can be avoided through hardening techniques. The hardening condition of the steel depends on the grade of the alloy. For example, the carbon-made ones are more prone to deformation than the austenitic-made steels. The latter is commonly used for custom fabrication.

The rates of the steel also vary. There are cases in which the austenitic ones need to have a hardening rate of 1,000 MPa, since it absorbs cold more frequently than the other types. However, the typical rate is around 800MPa.

Machining Process

The machining process is done with several considerations as it will define the shape of the steel. Machining is a laborious job, it requires experts to do the entire process. Initially, the steel has to be applied with lubricants to avoid any chipping. It is also important that the machine tool for machining is sharp enough to cut through edges efficiently, and with a reduce vibration feature. Machining can also be achieved chipped-free by means of adding an alloyed manganese sulfide.

Welding the Stainless Steel

The steels are welded to create a new structure. There are several types that can be welded but the composition of steel will affect the level of efficiency. The austenitic steels are perfect types to be welded. However, this type is also susceptible for corrosion especially when the material is thick. Other good welding steels are the martensitic, duplex and ferritic stainless steels.

Steels are great for custom fabrication but there are other materials considered to ensure strength and durability.
