Carbon Steel

Carbon Steel

Carbon steel is used in the manufacturing 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 (304SS)

Stainless Steel Type 304 (304SS)

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 than 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°F.  Continuous use of 304 in 800-1575°F range is 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.


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


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 (316SS)

Stainless Steel Type 316 (316SS)

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 it is not possible to anneal after welding and where maximum corrosion resistance is required.
