General Information

Description

Melt Practice


This austenitic stainless steel is initially electric-arc melted. Then as a refinement to the purity and homogeneity of the metal, 304LV is Vacuum Arc Remelted (VAR). This process yields a more uniform chemistry with minimal voids and contaminants. The “L“ means low carbon as compared to 304V.

Phosphorus 0.018
Sulfur 0.005

Physical Properties

Density 0.285 lbs/in3
Modulus of Elasticity 28.0 x 106 psi
Electrical Resistivity 720 μohms-mm
Thermal Conductivity 16.3 W/m K (100°C)

Thermal Treatment


A reducing atmosphere is preferred for thermal treatment but inert gas can be used. 304LV will fully anneal at 1010-1121°C in just a few minutes. The precipitation of carbides that decreases corrosion resistance in other 300 series alloys is controlled by a reduced carbon content in 304LV.

Applications


The chemistry of 304LV makes it less susceptible to sensitization. (Sensitization is the reduction in a material’s corrosion resistance due to exposure to elevated temperatures.) Because of this feature, 304LV is recommended when exposure to 427-649°C is likely. End uses include catheters, guidewires, small parts made from straightened and cut wire and orthodontic applications.

Surface Conditions


Stainless steels develop a highly polished appearance as they are drawn to fine diameters. Surface roughness can be less than 5 microinches RMS when processed using single crystal natural diamond dies and measured with a profilometer. Diameters over 0.040" are finished with polycrystalline dies and exhibit a rougher surface than natural diamond dies. Diameters over 0.100" have an even rougher surface because they are drawn with carbide dies. Additional finish treatments can enhance the surface of the wire.
