What is SCS14 equivalent to?

What is sCS14 material?
If you are looking for corrosion-resistant stainless steel parts, you may have already encountered SCS14, especially in the valve, pump, and casting industries. SCS14 is a Japanese JIS standard stainless steel casting grade (JIS G5121), belonging to austenitic stainless steel castings, commonly used in valves, pump bodies, flanges, fittings, and seawater systems.

 

What is the ASTM material equivalent for SCS14A?

ACI-ASTM CF8M (SCS14, SCS14A, J92900) Cast Stainless Steel. ACI-ASTM CF8M steel is an austenitic stainless steel formulated for casting. Cited properties are appropriate for the heat treated (HT) condition. CF8M is the designation in both the ACI and ASTM systems for this material.

 

What is SCS14 equivalent to?

SCS14 is a JIS standard for cast stainless steel, equivalent to CF8M, and has a similar chemical composition to 316 stainless steel but is optimized for casting. It is a common material for components like valve bodies, pump casings, and other parts that require high corrosion resistance, especially in chloride environments.

Standard	Equivalent Grade	Type
ASTM	CF8M	Cast version of 316 stainless steel
EN (Europe)	1.4408	Cast molybdenum-containing stainless steel
JIS (Japan)	SCS14	Cast austenitic stainless steel
W.Nr	1.4408	Equivalent to CF8M

 

What is the ASTM equivalent of 316 stainless steel?

ASTM standards corresponding to 316 stainless steel include ASTM A240 Type 316 (plate, sheet, and strip) or ASTM A276 Type 316 (bars and rods). Depending on the specific product form, other corresponding standards also exist, such as ASTM A312 TP316 pipe. The grade designation "316" refers to a specific chemical composition, whereas ASTM standards specify the material's form and properties.

Is SCS14 the same as 316 stainless steel?

Yes, SCS14 is the equivalent of 316 stainless steel. SCS14 is a Japanese standard designation for cast 316 stainless steel, which is known for its superior corrosion resistance due to the addition of molybdenum. This makes it a common material for components that require high durability and resistance to seawater and other corrosive substances.

 

What is the difference between SCS13 and SCS14? 

The main difference is that SCS14 has superior corrosion and pitting resistance compared to SCS13. SCS13 is equivalent to the common SUS304 stainless steel and is used for general industrial applications, while SCS14 is equivalent to SUS316 and is better suited for more corrosive environments like seawater or acidic wastewater.

 

CF8M vs 316

CF8M is the cast metal equivalent of wrought (forged or rolled) 316 stainless steel. They share a very similar chemical makeup containing 2% to 3% molybdenum, but they differ by manufacturing method and minor carbon allowance limits. 

 

What is the forged equivalent of CF3M?

The forged (wrought) equivalent of CF3M is Grade F316L under ASTM A182, which corresponds to standard 316L stainless steel. CF3M is the cast designation (under ASTM A351 or A743) featuring low carbon and molybdenum, matching the chemistry and corrosion resistance of wrought 316L.

 

Which is better, CF8M or CF3M?

Neither CF8M nor CF3M is universally "better"; choice depends on your project. CF8M (cast grade for 316) has higher carbon (up to 0.08%) for better strength at higher temperatures. CF3M (cast grade for 316L) has ultra-low carbon (up to 0.03%) to prevent weld decay and intergranular corrosion during welding.
