We are frequently welding En 24 and H11 /H13 type of mtl as a service

to the forging customers of ours

The successful procedure what we have adopted with our exp. is is as

follows

Stress relieve the job ( pre heat up to 650dig C )soak for 1hr/inch of

thickness allow to cool in furnace up to 300dig C

tak out the job wrap in ceramic wool

Weld the job

slow cool with insulation

Sr again

harden & temper to the desire value hope this may help u
