300 Series Heat resistant

DCG Alloys can supply a complete range of heat resistant stainless steel plate from 304H, 309/309S, 310/310S, 321/321H, and 347/347H to meet your most demanding needs.

Heat resistant stainless steel plate grades are resistant to scaling and retain good strength at high temperatures. They also offer excellent resistance to intergranular corrosion following exposure to high temperatures.

Duplex/Super duplex

DCG Alloys can supply Duplex 2304, 2205, and 2507 stainless steel plate products available to satisfy your strict corrosion and high strength requirements.

Duplex stainless steel is stainless steel plate containing relatively high Chromium levels (between 18% and 28%) and moderate amounts of Nickel (between 4.5% and 8%). The high corrosion resistance and the excellent mechanical properties of duplex stainless steels can be explained by their chemical composition and balanced (“duplex”) microstructure of approximately equivalent volume fractions of ferrite and Austenite. Alloys 2304 and 2205 are the most common grades. An outstanding feature of this stainless steel plate is its resistance to chloride stress corrosion cracking.

“Super” duplex grades have enhanced pitting and crevice corrosion resistance compared with the ordinary Austenitic or duplex types. This is due to the further additions of chromium, molybdenum, and nitrogen to these grades. Alloy 2507 is the most common “super” duplex grade.

Precipitation hardening

DCG Alloys provides a complete line of 17-4PH stainless steel plate for applications in offshore, food, pulp and paper, aerospace, and mechanical components and nuclear waste casks.

Precipitation hardening stainless steel plate, like the Martensitic types, can be strengthened (ie. hardened) by heat treatment. The mechanism is metallurgically different from the process in the Martensitic types. This means that either Martensitic or Austenitic precipitation hardening structures can be produced. These stainless steels combine high strength and hardness with corrosion resistance which is superior to that of the Martensitic Chromium stainless steels. All precipitation hardening stainless steel plate contains a relatively high Chromium content. Most applications of precipitation hardening stainless steel plate are for corrosion resistance or oxidation resistance and retention of strength at elevated temperatures.
