Given its versatility, steel can take different forms as a result of the wide range of fabrication techniques. Each steel fabrication technique however has both benefits and disadvantages. Due to the fact that the material is malleable, it can be transformed to other shapes through bending, welding, drawing, spinning, folding or machining. The fabrication majorly entails three processes; machining, welding and work hardening. When it comes to steel fabricators Pittsburg PA has the best.
Work hardening process involves deforming the alloys in attempt to strengthen them. Fabrication is a quick process and largely depends on the alloy grade. For instance, austenitic alloys have a higher hardening tendency than the carbon steels. It is commonly believed that any work hardening method should conform to the grades of the alloys.
Only austenitic alloys are commonly hardened through cold working. Other grades of alloys must undergo the thermal treatment process during work hardening. It is widely argued that work hardening is mainly suitable for the fabrication of austenitic and martensitic alloys. On the other hand, some alloys such as the ferritic family are not regarded as a perfect suite for work hardening. Unlike austenitic alloys which can reach a work hardening range of 1000MPa, most steels usually attain up to the maximum 800MPa range.
In case of cold drawing, steels can attain the tensile ranges of more than 2000MPa, especially steels with fine wire sizes. Size of the material is a major concern for work hardening since the tensile strength increases with increase in the diameter of a wire. Work hardening is also beneficial in a number of ways. For instance, the high rates of hardening ensure that the product is strong and corrosion resistant.
High level hardening is widely applied in production of cryogenic machinery, bolts and nuts, machine parts and hospital equipment. Arguably, martensitic alloys have high level resistance to corrosion as well as tensile strength. They have often been singled out for the manufacture of cutlery, valve parts, bearings and tools. Researchers have also claimed that work hardening increases the magnetic strength of material.
In cases of low magnetic value, steels can be upgraded through high levels of work hardening in attempt to increasing their magnetic strength. Similarly, hardening is also suitable for improving the functionality of the alloys. Subjecting steels to machinery is an ultimate way of eliminating the chipping effect. This usually requires extensive use of machining techniques since it is a complex practice.
Regular use of coolants and lubricants is a crucial step to take. Large tools can also be used to enhance the dissipation of heat as well as maintaining light cuts and constant feeds. Essentially, chip breakers can be used to deflect the debris. The mechanics should always select a machining tool that is able to reduce vibration while keeping the cutting sharp at all the times.
Welding is also a fabricating option that can be used to transform steels into different shapes. However, the quality of work output heavily depends on the grade of the alloy. Majorly, it is argued that austenitic and martensitic steels are more suitable for welding than ferritic steels. One should however get a professional to carry out these tasks.
