PROCLAD Heat Treatment


This service can be offered utilising either our Batch furnaces (1400mm high, 2400mm wide, and 5000mm long) or our Top Hat furnaces (up to 1500mm high, 3000mm wide, and 6500mm long).

Products requiring treatment can be placed in the furnace at a pre-set temperature with a ramp rate as required by our client's specification or an unrestricted temperature. After the furnace has equalised the load shall be soaked at approximately 880 - 960°C (actual time/ temperature to be specified in the heat treatment procedure). The load shall be withdrawn from the furnace followed by cooling in still air to ambient.

This process is typically prescribed for the following material grades:

API 5L grades A, B, X42 and in some cases X52 AISI 8630 & 4130; ASTM A182 F22
