304 / 304L REFRACTORY ANCHOR

This is one of the most widely used and oldest of stainless steel. This was originally called 18-8 which stood for its chromium and nickel content. It possesses an excellent combination of strength, corrosion resistance and fabricability. It is available in the widest variety of forms and sizes of any stainless steel. This can be effortlessly welded and is preferred for many deep drawn, spun or formed parts due to high ductility.

This was originally called 18-8 which stood for its chromium and nickel content. It possesses an excellent combination of strength, corrosion resistance and fabricability. It is available in the widest variety of forms and sizes of any stainless steel. Forging, heading and other hot working should follow uniform heating to 2100-2300 F (1149-1260 C). Sudden cooling is necessary to attain maximum corrosion resistance in finished parts. This alloy does not respond to heat treatment. Cold work will cause an increase in both hardness and strength.

Incoloy 800H / 800HT REFRACTORY ANCHOR

INCOLOY alloys 800H and 800HT have significantly higher creep and rupture strength than INCOLOY alloy 800. The three alloys have nearly identical chemical composition limits. However, chemical composition limits vary with carbon, aluminium and titanium. The carbon content of INCOLOY alloy 800 is 0.10% max with no limit on the lower end. The carbon content for INCOLOY alloy 800H is 0.05 to 0.10%, which is the upper end of the 0.10% maximum specified for INCOLOY alloy 800. The chemical limits for INCOLOY alloy 800HT are even more restrictive yet still within the limits specified for INCOLOY alloy 800H. The carbon content for INCOLOY alloy 800HT is further restricted to 0.06 – 0.10%.

Incoloy 800H and HT are ordinarily utilized as a part of temperatures above 1100F where resistance to creep and rupture is required. HT can be welded by the normal process utilized on stainless steels. 800HT wont get to be embrittled even after long stretches of use in the 1200-1600F range where numerous stainless steels get to be brittle. At the point when cold shaped, broadly the grain size delivers an obviously undulated surface called orange peel.
