Ultra Fine Stainless Steel Applications

Woven Wire Mesh -

Stainless steel is selected for its resistance to heat, wear, acid and corrosion characteristics. Although many different grades of steel are used in wire mesh due to their unique properties, T304 is the most common. Wire mesh made from stainless steel is used in all types of applications including: mining, food industry, chemical industry and pharmaceutical industry.

Wire Cloth -

Wire cloth is commonly found in industries ranging from aerospace, atomic energy, steel producers and railroads to sand, gravel, seed, grain, rubber and plastics. A list of usable applications consist of the following:

• Scalping of Metal
• Arrestor of flame sparks
• Containers for cleaning
• Burners for gas heaters
• Screen printing

• Dewatering of materials
• Shielding
• Medical implants
• Grids for batteries, fuel coils
• Gas diffusion

Wire Rope -

The flexible wire rope is most commonly used for running rigging applications. It is strong, medium flexible cable; commonly used for wire halyards. Each of the seven strands consist of 19 individual wires, which is oil free and highly polished. "BL" is the breaking load and "WLL" is the maximum working load recommended. 316 is the suggested alloy for corrosive enviornments.

Stretch in wire rope -
Stretch is the characteristic in all wire ropes, constructional stretch initially (as the individual wires 'bed down') and then as conventional elastic stretch.

Elastic Stretch -
Once a cable has bedded down it will obey Hookes Law; elastic stretch will be proportional to the load applied. Resistance to this stretch is determined by the modulus of elasticity.

Pre-Stressing -
Where stretch is critical to the application, constructional stretch can be eliminated by pre-tensioning or pre-stressing. This can be carried out during manufacture or swaging.
Pre-stressing is usually only applicable on large bridge structures and is not necessarily appropriate on structures where rigging screws and tensioning devices are used to take up any stretch.
Elastic stretch can be calculated by the following formula:
Elastic Stretch = (W x L) / (E x A)

W = Applied Load ( kN )
L = Cable length ( mm )
E = Strand Modulus ( kN/mm2)
A = Area of Cable = (D2 x pi) / 4 (where D= Dia of cable mm)

Typical values for E are:
1x19 = 107.5 kN / mm 2
7x7 = 57.3 kN / mm 2
7x19 = 47.5 kN / mm 2
Dyform = 133.7 kN / mm2

Break Load Example -
It should be noted that stainless steel wire rope and strand will start to distort at around 50% of its breaking load. It is therefore advisable not to load cables to more than 50% of their breaking loads.

To convert kN to KgF divide by 0.009807. To convert kN to LbF divide by 0.004448.
