Astm A582 For Type 303 Stainless Steel Sheet Coils Food Grade Gauge 14 20

What is 303 stainless steel

303 SS is a free-machining, austenitic stainless steel that is used primarily for parts requiring machining, grinding or polishing. The additional sulfur present in 303 assists in breaking up turnings which reduce drag on the cutting tool. This alloy offers good corrosion resistance in mild environments and good forming properties. It is non-magnetic in the annealed condition, is not hardenable by heat treatment, and can only be hardened by cold working. It is also difficult to weld, and may require filler rods and annealing.

The improved machinability of 303 stainless (UNS S30300) makes it ideal for screw machine applications, aircraft fittings, and fasteners. The additional sulfur that allows this product to be readily machinable also lowers its corrosion resistance compared to a grade like 304. Overall toughness is lower but still good despite the inclusion of sulfur, and is comparable to other austenitic grades of stainless steel. We offer 303 stainless in plate from 0.1875” to 4.000” thicknesses.

303 vs 304 stainless

303 and 304 have similar chemistry and both are iron alloys, however Alloy 303 was purposefully developed for ease of machining. The additional sulfur present in 303 assists in breaking up turnings which reduces drag on the cutting tool and increases machining speeds. AISI 303 is not weldable and has limited formability due to its sulfur content. AISI 304 is weldable and machinable. It has very good drawability as well. Its low yield strength and high elongation allow it to be formed into complex shapes.

Package and Delivery

1.Anti-collision package edge
All parts of the machine are covered with some soft materials, mainly the use of pearl wool

2.Fumigation wooden box:
Our wooden box is fumigated, do not need to check the wood, saving the transport time.

3.Whole tray packaging machine:
The tray is used as a carrier and package or product is stacked on the tray and fixed by strapping wrapping or gluing to form a handling unit for handling by mechanical equipment

4.Tray Package at the bottom of a solid iron socket for easy handling
