 AISI 304/304L, W 1.4301/W 1.4306, X5CrNi18-10/X2CrNi19-11

Diameter range:

0,5 mm – 150 mm


ISO 3290 G100-G1000


Unhardened Stainless Steel

AISI type 304 and 304L stainless steel balls meet requirements for an unhardened ball with excellent toughness and resistance to corrosion. Corrosion resistance may be increased through annealing. Both non-annealed and annealed balls are widely used in valves and related equipment.

Stainless type 304 and 304L balls are capable of resisting corrosion by such agents as oxidizing solutions, most organic chemicals, food stuffs and sterilizing solutions. They are moderately resistant to sulfuric acids. Non-magnetic properties available upon request. Applications include aerosol, sprayers, finger pump mechanisms, milk machine blenders, food processing equipment and medical applications.


Material Analysis AISI 304/304L

304: C= max 0.15%, Cr=17 - 19%, Mn=max 2.0%, Si=max 1.00%, S= max0.03%, P=max 0.045%, Ni=8-10%
304L: C=max 0.03%, Cr=18 - 20%, Mn=max 2.0%, Si=max 1.00%, S=max 0.03%, P=max 0.045%, Ni=8-12%


Mechanical Properties

Non-annealed hardness, uniform throughout, as measured on parallel flat surface is Rockwell "c" 25 to 39. Annealed hardness is Rockwell "B" 75 to 90. Annealing of Type 304 and 304L stainless steel balls is available (must be specified at time of quotation and order). At Rockwell "B" 75 to 90, standard.


HRC 25 – 39
