CF-3M: Corrosion Resistant Alloy Property Data

Stainless Steel SA351 CF3M, Butterfly valve

DESCRIPTION
CF-3M is a Fe-Cr-Ni-Mo alloy that is the cast equivalent of wrought, low carbon, AISI 316L stainless steel. The low carbon content of the alloy results in greater resistance to sensitization of the welds. Consequently, it is most commonly used in applications where post-weld heat treatment cannot be applied. Optimum corrosion resistance is reached after solution annealing at 1900 to 2050oF followed by rapid cooling. It has good resistance to organic acids and salts, sulphuric and sulfurous acids, phosphoric and phosphoric-sulphuric-hydrofluoric acid mixtures, sulfate and sulfite liquors, seawater and other chloride solutions, sodium hydroxide and steam. A modified form of the alloy, known as CF-3MA, has higher strength than the normal CF-3M. This is achieved by balancing the composition to produce a higher range of ferrite than the 20% present in the CF-3M grade.

ASTM A572 Gr 50 Steel Plates
Grade 50 is a high strength, low alloy steel that finds its best application where there is need for more strength per unit of weight. Less of this material is needed to fulfill given strength requirements than is necessary with regular carbon steels. Grade 50 is used in general plate applications when the plate will be riveted, bolted, or welded. Grade 50 is a Columbium-Vanadium steel that offers a minimum yield of 50,000 PSI. In addition, ASTM A572 Grade 50 is noted for its increased resistance to atmospheric corrosion. Grade 50 contains more alloying elements than plain carbon steel and thus is somewhat more difficult to form. Grade 50 is more difficult to cold work, but can be successfully bent or shaped but requires more force than plain carbon steel.

ANALYSIS

	Carbon (C)	Manganese (Mn)	Silicon (Si)	Vanadium (V)	Niobium (Nb)	Phosphorus (P)	Sulfur (S)
Over 1-1/2"	0.23	1.35	0.15-0.4	0.01-0.05	0.005-0.05	0.04	0.05
Up to 1-1/2"	0.23	1.35	0.4	0.01-0.05	0.005-0.05	0.04	0.05

Grade 50 conforms to ASTM A572

MECHANICAL PROPERTIES

Tensile Strength (PSI)	Yield Strength (PSI)	Elongation in 2"	Brinell Hardness
65,000	50,000	19	135

The above values are average and may be considered as representative of ASTM A572 Grade 50 Elongation in 8": 16%

APPLICATIONS

ASTM A572 Grade 50 is considered a "workhorse" grade and is widely used in many applications. Steel mills produce channel and heavy beams with Grade 50. It is commonly used in structural applications, heavy construction equipment, building structures, heavy duty anchoring systems, truck frames, poles, liners, conveyors, boom sections, structural steel shapes, and applications that require high strength per weight ratio.

MACHINEABILITY AND WELDABILITY

Machinability is rated at 66% of B1112. Average cutting speed 110 ft/min. Easily welded by all commercial methods.

HEAT TREATING

Grade 50 is generally used in the "as supplied" condition. Annealing, if required, can be done at 1700° F and slow furnace cooled.
