P460M is steels for pressure purposes —Part 5: Weldable fine grain steels,thermomechanically rolled.It’s used for making pressure vessel or boiler.
The meaning of the M,ML,ML2:
a) the basic series (P...M) min impact temperature 0℃，the impact energy is 27J.
b) series with low temperature properties down to -40 °C (P...ML1);
min impact temperature -40℃，the impact energy is 27J.
c) series with low temperature properties down to -50 °C (P...ML2).
min impact temperature -50℃，the impact energy is 27J.
The products of P460M thickness should be 5-63mm.
P460M can excessive post weld heat-treatment (PWHT) conditions,it can decrease the mechanical properties.
Where in stress relieving the intended time temperature parameter
P = T s (20 + lgt )x10 -3
Where T s is the stress relieving temperature in K and t is holding time in hours is exceeding the critical value of P crit. = 17,3 the purchaser should in his enquiry and order inform the manufacturer accordingly and, where appropriate, tests on simulated post weld heat treated samples can be agreed to check whether after such a treatment the properties specified in this standard can still be regarded as valid.
