304 Series

We are purchasing and selling large amounts of 304 stainless steel scrap and turnings on a daily basis.

AISI 304 is a stainless steel alloy composed of chrome ranging between 18% and 20% and nickel between 8% and 11%; its density equals 7.9 kg/dm3. 304L is characterised by a lower carbon (C) content, less than 0.035%, whereas 304 can accept up to 0.080%.

This steel is also known as “18-8 stainless steel” and it is mostly used to make cookware and cutlery; the expression “18-8 stainless steel pans and pots” has become customary by now. 304 steel scrap is one kind of scrap mostly dealt with on worldwide markets.

316/316 L Series

We are regularly purchasing and selling large amounts of AISI 316 and 316L (low carbon) stainless steel scrap and turnings.

AISI 316 is a stainless steel alloy composed of chrome ranging between 16% and 18%, nickel between 10% and 14% and molybdenum between 2% and 3%;

The presence of molybdenum increases the resistance to corrosion of the alloy in all natural surroundings: 316 or 316L stainless steel is largely used in the food and agro-food sector and it can be also applied in surroundings characterised by high humidity and salinity and, for this reason, it is widely used in the shipbuilding industry. Moreover, it is also used for screws for jewellery or for orthopaedic implants (for this reason, it is also referred to as “surgical steel”). 316 scrap is one kind of scrap mostly dealt with on the market: thousands of tons are handled each month.

302 HQ Series

It exhibits excellent corrosion resistance, much higher than that of grade 316 due to its high chromium, molybdenum, and nitrogen content.

Metco Inox is regularly dealing in 302 HQ on behalf of our customers.

309 Series

Grade 309 stainless steel has high corrosion resistance and strength compared to 304 stainless steel. The following datasheet gives an overview of grade 309 stainless steel.

310 Series

Grade 310 is a medium carbon austenitic stainless steel, for high temperature applications such as furnace parts and heat treatment equipment. It is used at temperatures up to 1150°C in continuous service, and 1035°C in intermittent service. Grade 310S is a low carbon version of grade 310.
Typical Applications Grade 310/310S is used in fluidised bed combustors, kilns, radiant tubes, tube hangers for petroleum refining and steam boilers, coal gasifier internal components, lead pots, thermowells, refractory anchor bolts, burners and combustion chambers,ETC.

317 Series

We deal regularly in this Grade as well.

321/347 Series

Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by Titanium (321) or Niobium (347) addition.
Grade 321H is a modification of 321 with higher carbon content, to provide improved high-temperature strength.
