Nitriding Heat Treatment Services

This process is typically done to surface harden low-carbon alloy steels such as 4130, 4140, 4340 and other chrome-moly alloys that contain elements such as manganese, molybdenum and chromium. Nitrogen molecules are injected into the steel to provide a hard wear resistant surface which also increases the strength of some shapes. Our nitriding process involves a slow rise to quench temperature above 900F, soaking metal to obtain nitrogen penetration depths from .005 to .015″ and a slow return to ambient temperature to reduce part distortion. Call for information on maximum size of components that we can handle. AHT also does carbo-nitriding where carbon is forced into the surface of alloy steels to create a harder surface then nitrogen alone. Call us for information on special fixtures that we can use to both straighten and nitride complex shapes that may be easily distorted due to their long length by any heating and cooling process.
