AISI 634, ASTM A564 Grade 634 is chromium nickel molybdenum stainless steel. AM 355 is a heat treatable austentic/ martensitic alloy (depending on the heat treatment). The properties of AM355 are that of strength of a heat treatable martensitic grades with the corrosion resistance of some of the chromium nickel austenitic grades. AISI 634, ASTM A564 Grade 634 is used for blades, knives, industrial cutters, discs, rotors, shafts and in similar parts where high strength is required at intermediate elevated temperatures.
The chemical compostion of ASTM A564 Grade 634 forging parts that we could produce is as followings
Iron (Fe) 73.2 to 77.7
Chromium (Cr) 15 to 16
Nickel (Ni) 4.0 to 5.0
Molybdenum (Mo) 2.5 to 3.2
Manganese (Mn) 0.5 to 1.3
Niobium (Nb) 0.1 to 0.5
Silicon (Si) 0 to 0.5
Carbon (C) 0.1 to 0.15
Nitrogen (N) 0.070 to 0.13
Phosphorus (P) 0 to 0.040
Sulfur (S) 0 to 0.030
FOllowing is heat treatment mechanical property of ASTM A564 Grade 634,Type 634,AISI 634,Alloy 634 forging steel turbine parts
Reduction of area MIn 25 %
Tensile strength MIn 1170 MPa
Yield strength Rp0.2 MIn 1070 MPa
Following is heat treatment way of ASTM A564 Grade 634 forged parts
Annealing
Heat to 1850/1900 °F(1024/1038 °C) and cool rapidly
Hardening
The alloy can be hardened by either sub-zero cooling or by a double-aging treatment. Hardening by sub-zero cooling will result in higher strength than that attained by double aging. "Condition" of the alloy by rapid cooling from 1710/1750 °F(932/954 °C) is required before either hardening treatnment.
After conditioning, the alloy is held at -100 Deg F for a minimum of 3 hours and then tempered at 850 °F for the best combination of strength and ductility. If, however, applications required better finish machining characteristics, higher impact strengths, or higher ductilities than are provided by an 850 °F temper, tempering temperatures up to 1000 °F may be employed. Optimum stress-corrosion-cracking resistance is provided by the 1000 °F temper.
1350/1400 °F(732/760 °C) for 3-4 hours, rapid cool; 825/875 °F (440/468 °C) for 2-3 hours , air cool. The 1350/1400 °F treatment results in carbide precipitation so that the material will completely transform to martensite when rapidly cooled to room temperature. The treatment at 825/875 °F after transformation provides further increases in strength and hardness.
