Stainless Steel, Nickel Alloys & Duplex Steels

Material Classes

What we stock, and what it is for.

Two principal families, each with its own economics. The right choice is usually the cheapest material that survives the service condition.

Nickel Alloys

15 grades stocked

Nickel alloys — also called superalloys or high-performance alloys — are highly engineered to offer a superior combination of high-temperature corrosion resistance, toughness, heat resistance and strength for the most demanding applications.

Characteristics

• Low breakdown and replacement cost
• Long life in specialised applications
• Costly, due to high Ni, Mo, Co & Ta content
• Low availability compared to stainless and carbon steel

Applications

Nuclear & Power Chemical Aerospace Furnace Components

Grades

• Nickel 200 / 201
• Monel 400
• Monel K 500
• Inconel 600
• Inconel 601
• Inconel 625
• Incoloy 800 / H / HT
• Incoloy 825
• Hastelloy C 276
• Hastelloy C 22
• 904L
• Alloy 20

Stainless Steel

21 grades stocked

Stainless steel is a group of alloys containing a minimum of 10% chromium. The chromium is what gives ordinary steel its stainless, corrosion-resistant character. It divides further into ferritic, martensitic, austenitic and duplex families.

Characteristics

• Better life-cycle and lower maintenance than carbon steel
• High fabricability, ductility, weldability and stability
• Economically viable where corrosion resistance is a must
• Easy availability compared to nickel alloys

Applications

Furniture & Kitchen Food & Beverage Pharmaceutical Automobile

Grade Index · 36 grades

Find your grade.

Search by designation, or filter by metallurgical family. Everything listed here is a grade we stock or source directly from our mill partners.

No grade matches that search. Try “316”, “Inconel” or “Duplex”.

Need something not listed — a different size, form or specification? Send us the requirement and we will source it.

Mill Partners · 10 sources · 8 countries

We buy direct from the mills that roll it.

Material arrives from Japanese, European, Korean, Taiwanese, South African and Indian producers — which is what keeps both the certification and the pricing honest.

Industries Served

Where the material ends up.

Domestic and international customers, across the sectors where corrosion, heat and hygiene decide the specification.

The Group · Three Companies

Industrial metals, wire ropes & tubes, precision SS tubes.

The promise on our brochure cover is carried by three companies under common management. One relationship, one set of standards — and a specialist desk behind each line of supply.
