MATERIALS

 

Carbon Steel

Carbon steel is used in the manufacture of Taylor Pipe Supports pipe hangers and supports. Excellent strength characteristics and adaptability to cold forming provide a well engineered design. By cold forming the steel, mechanical properties are increased, adding to the structural integrity of the fabricated hanger. 

Stainless Steel Type 304

This is the most versatile and one of the most widely applied of the 300 Series stainless steels. It has excellent forming and welding characteristics. The carefully controlled analysis of type 304 enables it to be deep drawn more severely then Types 301 and 302 without intermediate heat softening.

Type 304 also has outstanding welding characteristics. Post-weld annealing is not required to restore the excellent performance of this grade in a wide variety of mildly corrosive conditions.Type 304L does not require post-weld annealing and finds extensive use in heavy gauge components, where freedom from carbide weld precipitation is often required.

Corrosion Resistance: Excellent. Exceeding that of 302 in a wide variety of corrosive media including hot petroleum products and steam combustion gases.

Heat Resistance: Good oxidation resistance in intermittent service to 1600 degrees F and in continuous service to 1700 degrees F. Continuous use of 304 in 800-1575 degrees F range not recommended but often performs well in temperatures fluctuating above and below this range. Type 304L is more resistant to carbide precipitation and can be used in the above temperature range.

Annealing: Heat to 1850-2050 degrees F and cool rapidly. These grades cannot be hardened by thermal treatment.

Welding: Excellent. All standard methods. Use Type 308 rods or electrodes. Heavy welded sections in Type 304 may require post-weld annealing for maximum corrosion resistance. This is not required if Type 304L is used.

Stainless Steel Type 316

Type 316 is a molybdenum bearing grade. The addition gives this grade better overall corrosion resistance properties than types 301 and 304 and higher creep strength at elevated temperatures.Type 316 gives useful service at room temperatures in sulfuric acid of concentration lower than 15% and higher than 85%. It also resists chloride attack and is often selected for use in marine atmospheres.

Type 316L with its 0.03 maximum carbon content is used in applications where is not possible to anneal after welding and where maximum corrosion resistance is required.

Corrosion Resistance: Good resistance to a wider range or chemicals than Type 304. Highly resistant to the complex sulphur compounds used in Pulp and Paper processing. Also resists attack of marine and corrosive industrial atmospheres.

Heat Resistance: Good oxidation resistance in intermittent service to 1600F and in continuous service to 1700F. Continuous use of 316 in 300F/1575F range is not recommended but often performs well in temperatures fluctuation above and below this range. Type 316L is more resistant to carbide precipitation and can be used in the above temperature range.

Annealing: Heat to 1850F-2050F and cool rapidly. These grades cannot be hardened by thermal treatment.

Welding: Good characteristics suited to all standard methods. Use Type 316Cb, 316L or 309Cb filler rods or electrodes depending on application. Welded sections in Type 316 require post-weld annealing for maximum corrosion resistance (This is not required if Type 316L is used). Application include pulp and paper equipment, head exchangers, dyeing equipment, photographic developing equipment, propeller shafts, fittings and exterior architectural components in marine coastal areas.

Aluminium 5052 H32

5052 is one of the higher strength non-heat-treatable alloys. It has a high fatigue strength and is a good choice for structures subjected to excessive vibration. The alloy has excellent corrosion resistance, particularly in marine atmospheres. The formability of the grade is excellent and in the annealed condition it offers higher strengths than 1100 or 3003 grades.

5052 is often used in high strength sheet metal work, marine components, appliances, fuel and oil tubing.
