Mild Steel

Mild steel (known as carbon steel) is a general term for a range of low carbon steels that have good strength, with good properties for forming and welding. The amount of carbon found in mild steel varies, but is typically between 0.05% and 0.25%, but not exceeding 0.30%). It offers a cost -effective solution to many requirements, where its strength is utilised, but finishes such as powder / plastic coating or hot-dip galvanising are added to increase its life expectancy.

Common mild steel mesh applications include

  • Handrail safety infill mesh

  • Trailer ramps and sides

  • Industrial window guards

  • Machine guards

  • Pond covers

  • Gabion cages

  • Street Furniture

Stainless Steel (overview)

Steel can be mixed or alloyed with other elements to give it special properties.  However, plain steel corrodes easily, so where resistance to corrosion is required, stainless steels are often used.

Stainless steels are corrosion resistant metal alloy containing Iron (Fe), chromium (Cr) and nickel (Ni).  The chromium reacts with the oxygen to form a thin invisible layer of chromium oxide.  As a result of this, stainless steels can resist attacks by a range of acids, oxidisation, and other industrial chemicals and temperatures. Environmental benefits include no leaching compounds that may compromise its composition with elements such as water.  Furthermore, stainless steels are almost completely and infinitely recyclable and are also environmentally neutral and inert.

Stainless Steel Grade 304 (SS304)

Stainless steel type 304, also known as 1.4301 is part of the austenitic family with high chromium and low carbon content, which is what gives it its corrosion resistant properties.

This type of stainless steel is extensively found in food production facilities, non-medical laboratories, and many other hygiene conscious environments.

Typical Chemical Composition

Element C Mn P S Cr Ni Si Mo Cu N
Content % 0.15 2.00 0.045 0.030 17.00-19.00 8.00-10.00 1.00 0.75 0.75 0.10

Common stainless steel 304 mesh applications include

  • Commercial catering trays

  • Aqueous wash baskets

  • Parts cleaning baskets

  • Autoclave trays

  • Industrial cooking trays

Stainless Steel Grade 316 (SS316)

Stainless steel type 316, also known as 1.4401 is typically as SS304 but with the addition of 2% molybdenum (Mo).

This gives it increased resistance to general corrosion and pitting/crevice corrosion. This type of Stainless steel is a preferred for applications in extremely corrosive environments, and as such is specified on most medical, pharmaceutical and environments where harsh sulphur bearing water or halogen salts such as chlorides are present.

Element Mn P S Cr Ni Mo Si N
Content % 2.00 0.045 0.030 16.00-18.00 10.00-14.00 2.00-3.00 0.75 0.10

Common stainless steel 316 mesh applications include

  • Waste water treatment

  • Medical Sterilisation Trays

  • Curing trays (food)
