Stainless Steel CF3MN (316LN)

Stainless steel CF3MN is a low carbon, nitrogen enhanced austenitic stainless steel with high corrosion resistance and strength property. It’s typically used for elevated temperature applications. CF3MN is 21 Chromium-24 Nickel with Molybdenum and Nitrogen, generally it’s CF3M + Nitrogen. Thus, CF3MN is same as 316LN (316L + Nitrogen). The nitrogen in stainless steel CF3MN adds additional resistance to sensitization in some application.

CF3MN is listed in and standard. Casting UNS number is J92804 defined in . WW.CASTINGQUALITY.COM

Casting Quality Industrial provide CF3MN (316LN) castings by sand casting or investment casting (lost wax precision casting) process.

Our Services

  1. Sand Casting

    Casting Quality focus on Metal Parts industry, we provide professional service in Metal Casting field.

    Sand Casting is a popular metal form method, are suitable for all materiel, such as grey iron, ductile iron, malleable iron, carbon steel, stainless steel, aluminum and bronze.

  2. Investment Casting

    also named as precision lost wax casting, mainly suitalbe for carbon steel and stainless steel parts. We also provide grey iron and ductile iron and aluminum and bronze parts by investment casting. It can achieve the best appearance with good tolerance

  3. Shell Casting

    Shell casting method is a good option to replace investment casting and sand casting. the quality is better than sand casting parts, suitable for bulk production.
