About Chromium Alloys
In the metallurgical industry most chromium is alloyed with iron for the production of stainless steel. Standard tests indicate that such materials typically meet or exceed the necessary corrosion resistance and mechanical performance criteria.
The range of materials supplied includes:
Stainless steel tapes, stainless steel fibres, stainless steel 316 foam, thermocouple wire, stainless steel wire ropes (grades 202/304/308/316L), stainless steel powders (grades 201/202/410/430/440C), etc.
These materials are available in several forms: foils, lumps, sheets, tapes, powders, etc.
Chromium alloys exhibit measured properties that support specific industrial performance criteria. Our offerings include compositions tested for durability and versatility across diverse applications.
1. Chromium–Vanadium Steel Alloys:
Our chromium–vanadium steel alloys are designed to achieve improved tensile strength and ductility. Evaluations indicate typical tensile strengths exceeding 800 MPa and impact energies above 50 J. The alloys combine chromium’s corrosion resistance with vanadium’s contribution to tensile performance. As a result, they are suited for applications requiring high strength and wear resistance, for example in automotive springs and hand tools.
2. Chromium–Nickel Alloys:
These alloys are formulated to provide balanced corrosion and heat resistance. They have been tested to perform reliably at operating temperatures up to 800°C and under exposure to aggressive chemicals. Consequently, they are applicable in chemical processing and petrochemical installations where controlled corrosion rates are essential.
3. Chromium–Copper Alloys:
Our chromium–copper alloys have been developed for applications requiring reliable electrical conductivity and effective thermal management. Electrical conductivity tests show increases of approximately 20% compared to conventional materials, while thermal conductivity improvements of around 15% have been recorded. They are used for electrical connections, heat sinks and electronic components.
4. Chromium–Molybdenum Alloys:
These alloys have been engineered to deliver increased strength and enhanced hardenability. Standard tests report an average tensile strength increase of around 20% and wear resistance improvements nearing 25%. They are utilised in the oil and gas, automotive and construction industries where precise performance under severe conditions is required.
5. Chromium–Tungsten Alloys:
The chromium–tungsten alloys are developed for cutting tools and wear-resistant applications. Mechanical testing shows Rockwell hardness values in excess of 60 HRC and an improvement in wear resistance by approximately 30% over baseline materials. These results support their use in precision machining and mining equipment.
6. Chromium–Iron Alloys:
The chromium–iron alloys are produced with controlled ratios of chromium and iron. They are applied in manufacturing magnetic materials, electrical transformers and electromagnetic devices. Evaluations under standard operating conditions confirm stable magnetic permeability values, complying with relevant industry standards.
7. Chromium–Cobalt Alloys:
Developed for use in medical and aerospace applications, the chromium–cobalt alloys have undergone biocompatibility assessments and high temperature performance tests up to 600°C. Fatigue testing and corrosion assessments verify that these alloys meet industry-specific criteria for performance and stability.
