Physical Properties of 316 1.4401 316L 1.4404 Stainless Steel





When properly annealed, Alloys SA 213 316 and 317L are primarily austenitic. Small quantities of ferrite may or may not be present. When slowly cooled or held in the temperature range 800 to 1500°F (427 to 816°C), carbides are precipitated and the structure consists of austenite plus carbides.

Melting Range: 2450 to 2630°F (1390 to 1440°C)

Density: 0.29 lb/in3 (8.027 g/cm3)

Modulus of Elasticity in Tension: 29 x 106 psi (200 Gpa)

Modulus of Shear: 11.9 x 106 psi (82 Gpa)

Coefficient of Linear Thermal Expansion

The overall heat transfer coefficient of metals is determined by factors in addition to thermal conductivity of the metal. The ability of the 18-8 stainless steel pipe grades to maintain clean surface often allows better heat transfer than other metals having higher thermal conductivity.

Magnetic Permeability
Austenitic stainless steel tube are non-magnetic in the annealed, fully austenitic condition. The magnetic permeability of the Alloys 316 and 317L in the annealed condition is generally less than 1.02 at 200 H (oersteds). Permeability values for cold deformed material vary with composition and the amount of cold deformation but usually higher than that for annealed material.
