Alloys
Duplex stainless steels comprise a mixture of ferrite and austenite, producing a material with many of the advantages offered by both structures. They generally have comparable or better corrosion resistance to austenitic steels, with more than twice the yield strength, and are especially resistant to pitting corrosion and stress corrosion cracking in chloride environments. Duplex […]
Austenitic stainless steels are very tough and essentially non-magnetic materials that are alloyed to produce resistance to corrosion in a variety of environments. The basic 18% chromium/10% nickel grade (R31) has a very good corrosion resistance in many applications. This alloy can be refined (R31LC) or alloyed with molybdenum (R33,R34) for enhanced corrosion resistance or […]
Strength and corrosion resistance superior to many martensitic stainless steel alloys is achieved by precipitation hardening a low carbon martensitic or semi-martensitic stainless steel. This is accomplished by accurate alloying and a low temperature heat treatment, allowing machined parts to be age hardened with only minimal distortion and scaling. Depending upon the particular material composition […]
A protective passive oxide film can develop on steels with chromium contents above 12%, imparting to these steels “stainless” characteristics. By maintaining a suitable composition balance between carbon and chromium, a series of high strength stainless steels are produced (R23-R23XHC). Components cast in these alloys meet specific hardness and wear resistance criteria through closely controlled […]
Alloys of iron, carbon and silicon where carbon is present in excess of the amount which can be retained in solid solution are termed cast irons The common engineering grades contain Carbon in the form of flake graphite, but this can be modified with additions to a spheroidal shape. This imparts major improvements in strength […]
From a low carbon iron for electro-magnetic applications (S1), our range of low carbon steels (S3, S4) can be produced to meet specific strength and hardness requirements. Higher hardenability, wear resistance and sub-zero impact criteria are achieved through minor alloying additions and precise heat treatment control (R60-R67). An additional series of steels resistant to high […]
CORROSION RESISTANT STEEL GRADES
MARTENSITIC A protective passive oxide film can develop on steels with chromium contents above 12%, imparting to these steels “stainless” characteristics. By maintaining a suitable composition balance between carbon and chromium, a series of high strength stainless steels are produced (R23-R23XHC). Components cast in these alloys meet specific hardness and wear resistance criteria through closely […]
Steel alloys containing more than 20% chromium produce a protective, sustainable surface scale when exposed to high temperatures in oxidising atmospheres up to 1100 degrees C. When nickel and carbon are added to these alloys, a series of heat resisting alloys is produced to perform in an array of high temperature applications. Increased nickel content […]
The 99.5% cast nickel grade (R48) is designed to resist hot caustic solutions and can be alloyed to increase strength. Nickel-copper Monel type alloys (R47) have very good resistance to chloride corrosion. This grade can be supplied with additional silicon and age hardened (R47S) for increased strength where erosion-corrosion and galling occur in chloride containing […]
