Scrap of Stainless Steel 321 is also used by the recycling and metal industry as a material. This type of scrap is produced from the stainless steel containing titanium, which improves the material’s ability to combat corrosion. The 321 grade has also good stability against chromium carbide precipitation at raised temperatures,thus, it is suitable for applications operating at higher temperatures. The austenitic 321H has an enhanced resistance at higher temperatures than ‘321’ due to the inclusion of niobium.
That is why scrap metal recycling is considered to be one of the best environmentally friendly practices in the industrial world which saves tons of natural resources and reduces the requirements for extraction of new sources of raw materials. Stainless Steel 321 Scrap may be sourced from different areas such as product returns, fabrication and manufacturing scrap, and end of trade items. This paper scrap is then separated through methods of sorting and processing in order to be recycled and manufactured into new stainless steel related products.

Another benefit of recycling of SS 321H Scrap particularly by end users is that it is an inexpensive process. Collection, sorting, transportation, and processing all involve reduced energy consumption in comparison to making stainless steel from the bare essentials. Furthermore, the reuse of materials ensures that there is a lowered amount of emission of greenhouse gases that other manufacturing processes release into the atmosphere.
Stainless Steel 321 Scrap is used to replace machines and other metal items that are worn out, through processes such as recycling; this creates awareness of sustainable use through industrialists and the public. As these sectors focus on the use of the green products and materials, the levels of recycled stainless steel demand is ever increasing. Like most recycled metals, recycled stainless steel is as effective as stainless steel processed from collected raw materials.
Pricing for current products are about INR 110 to INR 170 per kilogram for the various types of products depending on their thickness, and the number bought, and the requirements for further processing. In a way, we often review the market price to ensure the value we give to our scrap is reasonable.
