Chemical Composition

.
Generally as per IS 1786:1985. However we maintain Carbon equivalent value to maximum 0.45%. (British Standard specifies 0.51% for grade 460).Carbon equivalent is determined by the following formula:Cequiv = C + Mn/6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15
.

Bend Properties

.
Easily satisfy International Standards. In India Bend 8 Rebend Tests are mainly carried out as per Indian 1786 8 British 4449 standards. BHAGWATI THERMEX bars meet all such requirements.
.

Weldability

.
Bhagwati Thermex bars are produced with C less than 0.25% an are suitable for all the main welding processes without any special precautions. No pre-heating or post-heating is necessary. No loss of strength at weld- joints.
.

Strain Ageing

.
Ageing resistant due to the manufacturing process and chemica composition.
.

Fatigue

.
Approved internationally for dynamically stressed structural sections.
.

Properties at High Temperatures

.
Thermex bars, unlike CTD bars, have a proven record resisting loss of strength at high temperatures as experienced during fires.
.

Corrosion Resisfance

.
More corrosion resistant than CTD bars. Cold working involved in CTD bars leads to surface stresses and consequent higher rate of corrosion - and, the protective scale layer falls off during twisting The Thermex process basically inhibits rate of scale formation an no cold working is involved.
