What is EN 1.4408 material?

What is 1.4408 material?

The primary equivalent standard for EN 1.4408 is the American standard ASTM A351 CF8M (J92900), representing the same cast austenitic stainless steel. Other equivalent grades include China's GB/T 12230 CF8M, Japan's JIS SCS14A, and the UK's BS3100 316C12. This material is also known as GX5CrNiMo19-11-2 under European standards. It is widely used in corrosion-resistant stainless steel castings, particularly for valves, pumps, flanges, and marine components.

Standard	Equivalent Grade
EN / DIN	1.4408 / GX5CrNiMo19-11-2
AISI / ASTM	316L (cast equivalent: ASTM A351 CF8M)
UNS	J92900 (CF8M), or S31603 (wrought equivalent)
JIS	SUS316LC (Cast)
ISO	G-X5CrNiMo19-11-2 (ISO 11971)

Note: 1.4408 is a cast steel, so although chemically similar to 316L, its mechanical properties and microstructure may differ due to the casting process.

1.4408/CFM8 stainless steel Mechanical Properties (As Cast, Heat Treated)

Property	Value
Tensile Strength	440 – 690 MPa
Yield Strength (Rp0.2)	≥ 220 MPa
Elongation (A5)	≥ 20%
Hardness (HBW)	≤ 230
Impact Toughness	> 60 J (at room temperature)
Density	~7.9 g/cm³

 

What is the hardness of 1.4408 material in HRC?

The hardness of EN 1.4408 (GX5CrNiMo19-11-2) cast stainless steel is typically measured in the Brinell (HB) scale rather than Rockwell C (HRC). In its annealed and cast state, it usually has a hardness of 130 to 220 HB.

 

What is the difference between 1.4408 and 316L material?

The core difference is that 1.4408 is a cast stainless steel (the European equivalent of American CF8M), while 316L is a low-carbon wrought stainless steel (formed by rolling, forging, or machining). While they share similar chemical and anti-corrosive properties, their manufacturing methods and strength profiles differ completely.

 

Is 1.4408 the same as CF8M?

Both ACI-ASTM CF8M steel and EN 1.4408 stainless steel are iron alloys. They have a very high 99% of their average alloy composition in common. There are 32 material properties with values for both materials.

 

1.4408 stainless steel applications

1.4408 (EN GX5CrNiMo19-11-2) stainless steel is a cast austenitic steel with excellent corrosion resistance, particularly in chloride-containing, acidic, and high-humidity environments. This makes it suitable for components in the marine, chemical, food, and pharmaceutical industries. Common applications include valves, pipes, heat exchangers, pumps, chemical reactors, parts of industrial machinery, and equipment for processing paper, textiles, and inks.
