In many applications, properties and performance requirements exceed those afforded by the standard commodity grades of stainless steel. To meet the challenge of special conditions, PAC Stainless stocks cold finished tubing in special chemistries to meet demanding conditions.

Alloy 400
This nickel-copper alloy is frequently employed in marine and chemical processing applications. This material works well over a wide temperature range (sub-zero to 1,000 F). It provides high corrosion resistance to flowing seawater and provides excellent resistance to de-aerated hydrochloric and hydrofluoric acids.

Size Range
Outside Diameter: 1/8" through 1"
Wall Thickness: .028" through .109"

Governing Production Specifications - ASTM B163 UNS N0440

Chemical Composition %	Ni	Cu	C	Fe	Mn	Si
	63.0 min.	11.0 – 15.0	0.3 max.	2.5 max.	2.0 max.	0.50 max.

Alloy 625
This austenitic based nickel super-alloy is employed in applications in the nuclear power, offshore marine and aerospace industries. Extremely tough and resistant to chloride induced stress corrosion cracking, the material derives its excellent performance characteristics from the interaction of a niobium addition with molybdenum.

Size Range
Outside Diameter: 3/8” through 3/4"
Wall Thickness: .035” through .095”

Governing Production Specifications - ASTM B444, B829 UNS NO6625

Chemical Composition %	Ni	Cr	Mo	Nb + Ta	Fe	C	Mn	Si	Al	Ti
	58.0 min.	20.0 – 23.0	8.0 – 10.0	3.15 – 4.15	5.0 max.	0.10 max.	0.50 max.	0.50 max.	0.40 max.	0.40 max.

317/L
This austenitic stainless steel features increased Molybdenum content compared to 316/L. The grade is often employed for pulp and paper mill equipment, chemical processing and semi-conductor system applications. It provides enhanced resistance to stress corrosion cracking in process environments where chlorides or other halides are present.

Size Range
Outside Diameter: 1/8" through 3/4"
Wall Thickness: .035” through .095

Governing Production Specifications - ASTM A213 / ASME SA 213 (average wall)

Chemical Composition %	Cr	Ni	Mn	Mo	C	Si	P
	18.0 – 20.0	2.0 max.	28.0 – 34.0	3.0 – 4.0	.035 max.	.75 max.	0.04 max.

316/L Cleaned and Capped for Oxygen Service
This instrumentation tubing is specially prepared for use in an oxygen-enriched environment. This is achieved through a meticulous cleaning and drying process. After passing through inspection to insure requirement adherence, end caps are placed on the cleaned tubes to keep the cleaned I.D. from post-cleaning contamination. Finally, the tubes are packaged in plastic bags to further insure a contaminant free product.

Size Range
Outside Diameter: 1/8” through 1.00"
Wall Thickness: .035” through .120”

Governing Production Specifications - ASTM A213 (average wall) and ASTM A269
