EN 10088-1 Physical Properties of Stainless Steel
The table shown is based on the reference data presented in EN 10088-1. Only a sample of the information available is shown. This is intended to show the scope of information available through representative figures for the most commonly used stainless steel tube types. A separate table indicates some of the grades that have been grouped together.Sifat Fisik Table

Units for the sifat fisik
‘Density’
The units are kg/m3 and are assumed to be for ambient temperature only.
‘Modulus‘
This is the ‘elastic’ or ‘Young’s’ modulus. Sometimes expressed as ‘E’. Values at ‘ambient’ 20C and 400C only are shown. The units are kN/mm2
EN 10088-1 has values in 100-degree steps up to 300, 400 or 500。C, depending on the steel ‘family’ involved.
‘Expansion’
The thermal expansion figures shown are an average between 20。C and 10C only. BS EN 10088-1 has values shown as averages between 20 and 100, 200,300,400 and 500 C, depending on the steel ‘family’ involved.
The units are ‘ 10-6 x K-1 ‘. This represents the increase (or decrease) in length that a 1 metre length of material will expand (or contract) if the temperature is changed by 1 degree Kelvin (which can be taken as 1 degree Centigrade for practical purposes).
So a value of ’10’ indicates that a 1 metre length of steel expands by 0.000010 metres (0.010mm) if the temperature rises from 20 to 21 C.
‘Conductivity’
The thermal conductivity values are for 20C only. The units are W/m.K.
This represents the amount of heat, in watts, that is conducted by the material, where there is a temperature difference of 1-degree Kelvin. (This represents a one-metre cube of material, with a 1-degree temperature difference on opposite faces)
‘Specific Heat’
This is shown in BS EN 10088-1 as ‘Specific thermal capacity’ at 20C. The units are J/kg.K ie ‘Joules per kilogram x degrees K’
‘Resistivity’
The units of ‘electrical resistivity’ are ‘ohm.mm2/m’ and are shown at 20C, as shown in BS EN 10088-1. These units are the same as ‘micro-ohm.m’.
