Material Key |
|
A1 Stainless Steel - also known as grade 303. A general purpose grade of stainless steel but with better fabrication/machining properties than grade 304 |
|
A2 Stainless Steel - also known as grade 304 or 18/8. A general purpose grade of stainless steel. |
|
A4 Stainless Steel - also known as grade 316 or 18/8/3. A higher corrosion resistant, marine grade of stainless steel. |
|
A4-80 Stainless Steel - identical corrosion resistance to A4-70 but with a higher tensile strength equivalent to that of 8.8 high tensile steel. |
|
Aluminium - Alumium is a lightweight, strong and corrosion resistant material. As the temperature lowers, aluminium actually increases in strength. It is also non-magnetic, carries a current and does not spark easily. |
|
Black oxide high tensile steel class 12+ - a high tensile non-stainless grade with a black oxide finish offering limited corrosion resistance |
|
Brass - offers an attractive, corrosion resistant finish. |
|
Bright Zinc Plated (BZP) Steel - non-stainless standard steel grade offering a basic level of corrosion resistance. |
|
Bright Zinc Plated (BZP) high tensile steel class 10 - a higher tensile non-stainless grade for nuts, with a basic level of corrosion resistance. |
|
Bright Zinc Plated (BZP) high tensile steel class 8 - the general purpose non-stainless grade for nuts, offering a basic level of corrosion resistance. |
|
Copper Alloy - Copper has good corrosion resistance and high tensile strength, allowing it to withstand high-pressure and high temperature conditions. It is a highly ductile and malleable material, enabling copper washers to create tighter seals and withstand vibration better than steel. Copper also provides excellent thermal and electrical conductivity. |
|
Duplex Stainless Steel 1.4462 - a type of stainless steel, which has greater corrosion resistance than A4 / 316 and a high tensile strength of minimum 700 N/mm2. Also known as 318LN. |
|
Plastic (Nylon Polyamide) - a tough lightweight plastic, strong at low temperatures, with excellent resistance to chemicals, and features favourable sliding friction behaviour. |
|
Plastic (Black Polylethylene) - has good barrier properties and good chemical resistance against, acid, greases and oil. |
|
Zinc Flake coated high tensile steel class 8 - a high tensile non-stainless grade for screws and bolts and nuts. Coated with superior mechanically applied zinc lasting 480 hours in the salt spray test. |
