Stainless steel is a material that holds the capacity to work smoothly in a corrosive environment. Here, both grades, i.e., 304 and 316 stainless steel, offers outstanding mechanical properties and contains nickel and chromium in high amount. These two elements provide exceptional corrosion resistance to forge fittings. Additionally, austenitic stainless-steel grades are capable of going through welding and forming procedures. Hence, these two grades of stainless steel are commonly useful in many applications. Here is the difference between stainless steel 304 and 316 forge fitting.
Stainless steel 304 forge fitting
Here, grade 304 of stainless steel is the most common austenitic stainless steel. The material consists of high nickel content between 8 and 10.5 % by weight. Along with this, it contains a high amount of chromium of approximately 18 to 20%. Besides, several other major alloying elements are present such as manganese, silicon, and carbon. Also, it shows the presence of iron as the alloying member. Due to nickel and chromium in a higher amount, 304 Stainless steel forge fitting indicates excellent corrosion resistance.
Applications of stainless steel 304 forge fittings
These stainless steel 304 forge fittings are useful in appliances such as refrigerators and dishwashers. Besides, commercial food processing equipment requires stainless steel 304 forge fittings. Stainless steel 304 forge fittings work well in environments containing corrode standard carbon steel. Also, heat exchangers and water management piping system require these forge fittings.
Stainless steel 316 forge fitting
Stainless steel 316 forge fitting is similar to 304 grades. Only the difference is that 316 stainless steel contains a higher amount of chromium and nickel. Also, stainless steel 316 forge fittings include various elements like silicon, manganese, and carbon. Additionally, iron shows the majority in the grade of 316. Chemical composition is only the significant difference between 304 and 316 stainless steel. Stainless steel 316 forge fitting contains a considerable amount of molybdenum, about 2 to 3 % by weight where it is in trace amounts in stainless steel 304. The presence of high molybdenum increases the corrosion resistance of 316 forge fitting.
Applications of Stainless steel 316 forge fittings
These fittings are considered as one of the most suitable choices for marine applications. Other than this, they are useful in chemical processing and storage equipment plants. Besides, refineries and medical devices require SS 316 forge fittings.
