SS304 – Sabot.
This Grade 304 is the standard "18/8" stainless steel clips & solids; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. This scrap category shall contain a minimum of 7% Nickel, 16% Chrome and have a maximum of 0.50% Molybdenum, 0.50% Copper, 0.045% Phosphorous & 0.03% Sulphur and free from harmful contaminants.
SS 316
Grade 316 is the standard molybdenum-bearing grade. This contains higher percentage of Molybdenum and Nickel than SS 304. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
SS 316L
Grade 316L is the low carbon version of 316 and is immune from sensitization (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm).
Saves – Old Zinc Die Cast Scrap (ZINC)
Shall consist of miscellaneous old zinc base die castings, with or without iron and other foreign attachments. Must be free of borings, turnings, dross pieces, chunks, melted pieces and skimmings. All un-metalables, dirt, foreign attachments and volatile substances (such as rubber, cork, plastic, grease, etc) are not permissible.
Battery Scrap
Rains – Scrap drained /dry whole intact lead
Lead is used for manufacturing batteries and after completion of its life; this gets converted in to lead acid battery scrap. These batteries should be free from any liquid. Outer cases can either be of plastic or rubber and be complete including caps. Non-lead (nicad, ni-fe, carbonaire, etc.) not acceptable.
