Technical Data

Material	Bar Stock	Forging	Designator
316 SS 316L SS	ASTM A479/A276	ASTM A182/A314	SS 6L
316L VAR SS 316L VIM-VAR SS	ASTM A479/A276 SEMI F20		6LV 6LW

Working Pressure

• Working pressure shown are calculated according to ASME B31.3 and B£!.1 at ambient temperature
• To get to the allowable working pressure at elevated temperature, use the allowable working pressure at ambient temperature to multiply the elevated temperature factors.

Working Temperature

Material	Minimum Temperature	Maximum Temperature
316 SS	-325°F (-198°C)	1000°F (538°C)
316L SS 316L VAR SS 316L VIM-VAR SS	-325°F (-198°C)	850°F (454°C)

Ordering Information

Add the material designator as a prefix, cleaning, and packaging code as a suffix to the basic ordering number to get the complete ordering number.

Cleaning and Packaging

• FC-01 Standard Cleaning and Packaging is applied for general industrial procedures. No suffix is needed.
• FC-02 Special Cleaning and Packaging, to ensure compliance with product cleanliness requirement as stated in ASTM G93 Level C. Add “-F2” as a suffix when needed.
• FC-03 Ultra-High Purity Process Specification is applied to products with wetted surface roughness finished to an average of Ra 5 μin. (0.13 μm). Add “-F3” as suffix when needed.

Cautions

Dimensions are for reference only and are subject to change. Welding of the same material is more advisable considering the same coefficient of expansion, lower possibility of poor weld, out-of-roundness or dimensional changes. Tungsten Inert Gas Welding (TIG) is recommended.
