Stainless steels are iron alloys with a minimum of 10.5% chromium. The rust resistance combined with Stainless Steel’s resistance to high and low temperatures means that it can be used for a very broad variety of applications where hygiene and sterilisation are required.
All Stainless Steel has a high resistance to corrosion. Low alloyed grades (Grade 304) resist corrosion in atmospheric conditions; highly alloyed grades (Grade 316, Marine Grade) can resist corrosion in most acids, alkaline solutions and chloride bearing environments.
Fabrication Methods
Stainless Steel can be cut, shaped and joined using:
- TIG Welding
- Press brake bending
- Punching
- Sheared and sawn
Finishes
Duffys offer a range of finishes for stainless steel including:
- Brushed or Satin finish
- Electropolished finish
- Mirror polished finish
Applications
Stainless Steel is often used in the pharmaceutical, agricultural and catering sectors for its corrosion resistance, cleanliness and durability.
The aesthetic appeal of Stainless Steel makes it a very popular choice for many in domestic and commercial applications. It maintains a fresh, clean long term appearance, lasting years.
Stainless Steel grade 304 is used to manufacture:
- Staircase handrails
- Kitchen and canteen furniture
- Machine parts
- Cabinets and shelving
- Tables, trolleys and racks
Stainless Steel grade 316 is used to manufacture:
- Boat fittings and structural members
- Architectural components
- Food and beverage processing equipment
- Hot water systems
- Plant for chemical, petrochemical, mineral processing
