Notes
1. The use if sulphide modification manufacturing techniques for these grade is permitted
2. The following elements may be present to the limits stated:
A copper 0.25%
B nickel 0.25%
3. Limits specified are for soluble or total aluminium
4. Carbon equivalent(CE) is calculated from the following equation:
CE=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15
5. Applies to niobium and Vanadium only, However, Niobium greater than 0.01% is not permitted.
6. Applies to niobium, Vanadium and titanium only, However, Vanadium greater than 0.10% is not permitted.
Coating type:
Zinc coating
Hot-dip galvanized coating standard AS/NZS4680 AS4750 or AS/NZS 4792
Type: Circular hollow section
External Dimensions(d0 d and b) ±1% with a minimum of ±0.5mm and a maximum of ±10mm
Thickness (t) For d0 ≤406.4mm:±10% For d0>406.4mm ±10% with a max of ±2mm
Out of roundness (o) 2% for hollow section having a diameter to thickness ratio not exceeding 100( see note 1)
Straight (see note 3)0.2% of total length
Mass(m)per unit length :not less than 0.96 time the specified mass(note 4)on individual lengths
Type: Square and rectangle hollow sections
External Dimensions(d0 d and b)±1% with minimum of ±0.5mm
Thickness(t)±10%
Concavity /convexity (see note 2) Max 0.8% or 0.5mm,whichever is greater
Squareness of side 90°±1°
External corner profile see table 4
Twist(v)2+.5%mm/m length
Straightness See note 3: 0.15% of total length
Mass(m)per unit length :not less than 0.96 time the specified mass(note 4)on individual lengths
Notes:
1. Where the diameter to thickness ratio exceeds 100,the tolerance on out-of-roundness becomes the subject of agreement between the manufacturer and purchaser.
2. The tolerance on convexity and concavity is independent of the tolerance on external dimensions.
3. The straightness tolerance applies to straightness on any one plane.
4. In lieu of any other requirement, the specified mass is considered to be the nominal mass as noted in Clause 16
TESTING
Tensile test and impact test
Cold flattening test
