Can I treat the surface of weather resistant steels to hasten the weathering process, and how do I maintain the surface colour?
Weathering steel grades include XLERPLATE® steel AS/NZS 3678 - WR350 and XLERPLATE LITE® steel AS/NZS 1594 - HW350.
BlueScope Steel does not recommend applying chemicals to hasten the weathering process and application of acid may pit the steel.
During normal conditions, the steel 'weathers' to an orange/brown patina. To maintain this patina, a clear lacquer can be applied but the coating must be maintained.

Will the grades from the 1995 version of the standard be available after the roll out of the 2008 version of AS 1548?

How does the strength of steel vary with increasing temperature?
For most plain carbon manganese steels the yield strength decreases approximately linearly with increasing temperature at the rate of around 0.1% of room temperature strength per 1°C increase in temperature. This means that most steels have about 50% of their room temperature strength at 500°C.
Above this temperature, the rate of softening increases more rapidly. Also other factors such as creep and oxidation become important at higher temperatures and can further increase the rate of softening. For these reasons, plain carbon steels are not generally suitable for applications above 450°C.

When product is supplied and certified by BlueScope Steel to a particular grade and standard, will it comply to some other standard?
The material supplied by BlueScope Steel is certified to the grade originally ordered. Because not all XLERPLATE® steel or XLERPLATE LITE® steels within a batch are individually tested, the specific properties for any particular plate are not known, and they can therefore not be reapplied to another Standard or grade. Where this situation arises, contact XLERPLATE® Customer Service on 1300 135 004. The customer service team will be able to assist in determining what product has been individually tested within a given batch. Product that has been tested may be reapplied, PROVIDED the test results comfortably meet ALL the requirements of the new grade or Standard. Product that was not individually tested must be tested to the requirements of the new grade or Standard.

How do I know if the XLERPLATE® steel product I have received is the material which was used as the basis for batch testing product?
The material identification (XLERPLATE® steel serial number) of the particular material unit tested is noted on the test certificate. Check if the XLERPLATE® steel serial number you have received corresponds with that shown on the test certificate as the tested unit. If there is no corresponding serial number, contact your distributor or BlueScope Steel Direct on 1800 800 789 to obtain the correct test certificate.

Can I order XLERPLATE® product which has been ultrasonically tested at the Mill? If so, what standard should I specify?
Only material which is rolled on the plate mill can be ultrasonically tested. Therefore, XLERPLATE LITE® steel cannot be ultrasonically tested as it originates from the hot strip mill.
Ultrasonic testing must be specified at the time of order. Ultrasonic testing is generally carried out to AS 1710, but testing to International Standards may be done on request.
-
When should I order ultrasonically tested XLERPLATE® product?
AS 4100 and AS 1554 Standards provide the guidelines for when ultrasonic testing should be specified. As a general rule, whenever the final product or application is of a critical nature, eg. there may be fatigue or heavy machining to be carried out; or where welds are subject to final ultrasonic inspection; the parent plate should be ordered with ultrasonic testing. AS1710 Level 2 is the most commonly specified Standard. Whilst all care is taken during manufacturing, unless the XLERPLATE® steel has been ordered ultrasonically tested, there is no guarantee that it will meet the requirements of AS 1710, if subsequently tested. It is the customers' responsibility to specify ultrasonic testing and the level required, based on their knowledge of the XLERPLATE® steel’s end use application and final weld ultrasonic testing requirements.
