STOCK RANGE
PRODUCT DESCRIPTION
13/8 PH VAR is in a family of martensitic precipitation
hardening stainless steel along with 17/4 PH and 15/5 PH.
It is produced as a consumable electrode, vacuum arc
remelted product offering excellent transverse toughness
and ductility even in large section. High strength is
developed by a simple low-temperature heat treatment. The
various H conditions in the table below indicate the
property combination achieved by heat treatment at the
temperature shown in degrees F. Due to the chemical
composition and controlled melting practise, 13/8 VAR has
an essentially ferrite-free microstructure. This material has
a typical density of 7.8kg/dm3.
Round Bar
: 5/16 to 4 Diameter
(7.94 to 107.95mm)
MACHINABILITY
Average cutting speed 80ft/min. 35-40% average (based on
100% for AISI 1212 steel). Similar to 17/4 PH.
CORROSION RESISTANCE
Superior to straight chromium grades like 410, approaching
corrosion resistance of the chromium nickel grades. In
many corrosive media it is equal to such grades as 302.
Corrosion resisting properties will be affected by surface
finish and aging heat treatment.
WELDABILITY
Excellent. Readily weldable by all commercial processes.
