What is 153 MA-CD?
153 MA-CD is 153 MA supplied in the CD condition — pick for machined fasteners, pins and small bar parts where tighter tolerance and higher yield strength are wanted. 153 MA-CD has a yield strength of 550 MPa (79.8 ksi) and a tensile strength of 780 MPa (113 ksi) — stronger than 83% of stainless steel grades. Elongation at break is 25% and the elastic modulus is 200 GPa (29 Msi). 153 MA-CD has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,400°C (2,552 °F). A is the default condition FabDigit quotes; CD is available on request or by drawing note.

Working with 153 MA-CD
Is 153 MA easy to machine?
Machine like a gummy austenitic: rigid setups, sharp positive-rake carbide, 15–25 % lower surface speed than 304, heavy feed and copious flood coolant to avoid work hardening and built-up edge.
Can 153 MA be welded?
Readily welded by GTAW/GMAW/SMAW with no preheat and low heat input; use over-alloyed heat-resisting filler (253 MA, 22.12.HT or 309/309Si), avoid interpass temperatures above ~150 °C and long dwell in the 600–850 °C σ-phase range.
Can 153 MA be formed, bent or molded?
Cold forms well but work hardens faster than 304 — allow larger bend radii, more press tonnage and interstage annealing at 1050–1100 °C; hot work at 1150–900 °C followed by rapid cooling.
What surface finishes work on 153 MA?
Pickle and passivate after hot work or welding to restore the Cr/Si oxide film; mechanical polishing and glass-bead blasting are fine, and no anodising or plating is normally applied.

153 MA-CD — frequently asked
What is 153 MA-CD used for?
153 MA-CD is typically used for furnace and boiler parts, exhaust system components and kiln hardware. In short: cerium-alloyed heat-resisting austenitic; lighter-duty 253 MA; oxidation resistant to 980 °C.
What is the yield strength of 153 MA-CD?
153 MA-CD has a typical yield strength of 550 MPa (79.8 ksi) and a tensile strength of 780 MPa (113 ksi) — stronger than 83% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is 153 MA-CD easy to machine?
Not especially — machinability is rated fair (42/100, better than 79% of stainless steel grades). Machine like a gummy austenitic: rigid setups, sharp positive-rake carbide, 15–25 % lower surface speed than 304, heavy feed and copious flood coolant to avoid work hardening and built-up edge.
Can 153 MA-CD be welded?
Yes — weldability is rated very good (78/100). Readily welded by GTAW/GMAW/SMAW with no preheat and low heat input; use over-alloyed heat-resisting filler (253 MA, 22.12.HT or 309/309Si), avoid interpass temperatures above ~150 °C and long dwell in the 600–850 °C σ-phase range.
What surface finishes work on 153 MA-CD?

Can 153 MA-CD be formed, bent or molded?
Cold forms well but work hardens faster than 304 — allow larger bend radii, more press tonnage and interstage annealing at 1050–1100 °C; hot work at 1150–900 °C followed by rapid cooling.
What is the maximum service temperature of 153 MA-CD?
153 MA-CD is rated for continuous use to about 1,000°C (1,832 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 153 MA-A and 153 MA-CD?
A is the default condition — standard stocked condition for plate, sheet, bar and tube; maximum ductility and best high-temperature oxidation behaviour. CD: pick for machined fasteners, pins and small bar parts where tighter tolerance and higher yield strength are wanted. Yield strength is 340 MPa in A versus 550 MPa in CD.
