Stocked through a wide range of sizes, in either mechanical tube, casing or DOM (drawn over mandrel) product forms.

These grades of low alloy steel containing Chromium and Molybdenum are the most widely used alloy for oil patch applications. Usually supplied in the hardened and tempered condition at 22 HRC max. They also find favour in many applications requiring higher strength levels up to 150 KSI 0.2% PS. The grade is not NACE MR0175 approved in these conditions, and should not be used in environments containing H2S.

The hardenability limitations of this grade (depth to which it will harden / obtain the specified mechanical properties after heat treatment) must always be taken into account when designing and selecting equipment.

Mechanical Properties(T=-20°C if not differently stated)

Impact Test

The shown values are related to a longitudinal specimen having a width W = 10 mm. If W is lower than 10 mm, the measured energy value in J must be transformed on the basis of the formula: KV = (KVmeasured x 10) / W.

Machinability

Our material allow a much better performance in machinability than the standard foreseen by the norm. The cutting speed, for 10 minutes life of the cutting edge, is equal to 465 m/min, exceeding the norm by almost 50%.

Weldability:

The material have good welding properties thanks to low carbon equivalent content (Ceq 0.49% max). This means that in standard conditions, tubes can be welded without pre-heating.

Heat Treatments

Approximate transformation temperatures are: Ac1= 715 °C Ac3 = 810 °C.
The austenitisation temperature recommended for normalising heat treatment is 880 °C.
