What is CA6NM material?
Description. Type CA6NM is an iron-chromium- nickel-molybdenum alloy that is hardenable by heat treatment. It is similar in general corrosion resistance to type CA15, but the addition of nickel and molybdenum to the CA6NM composition improves its resistance to attack by sea water.
Is CA6NM stainless steel?
ASTM A743 CA6NM alloy is a martensitic stainless steel typically used in energy industry -runners and hydraulic turbine components- due to its superior toughness, yield and fatigue properties.
What is astm 743?
ASTM A743 / A743M – 21 Standard Specification for Castings, Iron-Chromium, Iron-Chromium-Nickel, Corrosion Resistant, for General Application.
What is ASTM A487?
Standard Specification for Steel Castings Suitable for Pressure Service. This specification covers low-alloy steel and martensitic stainless steels in the normalized and tempered, or quenched and tempered conditions, suitable for pressure-containing parts.
What is ASTM A487 CA6NM?
ASTM A487 Grade CA6NM Class A, Heat-Treated – Martensitic Stainless Steel – Matmatch.
What is CA15 material?
SS410 is a Martensitic stainless steel with corrosion resistant property. The casting grade is named as CA15 (J91150) in standard of ASTM A743/A743M and ASTM A217/A217M and ASTM A487/A487M only. It’s a cheap stainless steel with good hardness.
What is CF3M material specification?
CF3M is a cast austenitic corrosion resistant alloy material for pressure containing parts, which covered by ASTM A351, ASTM A743 and ASTM A744 standard. The difference between CF3M and CF8M is carbon content; CF3M has only 0.03% carbon. CF3M generally is named as stainless steel 316L in ASTM A240 standard.
What is A487 material?

What is f6 material?
ASTM A182 F6a is a forged martensitic stainless steel with 13 wt. % chromium. Martensitic stainless steels can be high-carbon or low-carbon steel alloys.
What is ASTM A216 WCB?
A216 WCB is carbon steel castings for valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding.
What kind of filler is used for welding CA6NM?
When this process is selected, preheating and post weld heat treatment are required of the piece under reparation. El que no puede andar, se sienta. Type 309 welding filler metals are often used to make repairs of small flaws in CA6NM casting uncovered during machining – especially after near to final machining.
Can you use martensitic wire to weld CA6NM stainless steel?
For that areas under high stress and where the pitting is greater than 10% of the base material thickness, it can be appropriate to weld (after the “buttering”) with a martensitic wire or stick steel (E410 NiMo for instances) because this filler material has very similar physical and chemical properties than that of the ASTM CA-6NM stainless steel.
Can a CA6NM be welded without a PWHT?
The PWHT is definitely recommended for the CA6NM whenever possible, but the new super-martensitics are designed to be welded without PWHT. They are coming up with amazing things all the time!
What kind of bead to use to weld CA 6nM?
Use 410 Ni-Mo and with stringer beads with sufficient overlap use the temper bead approach and allow the weld region to cool to below 212 deg F. This is important to allow fresh martensite to form and become tempered during subsequent weld passes. The 410 Ni-Mo will match the CA 6NM in service and is very ductile material.
