Nickel-added high-performance weathering steel
The technology employed in the development of this steel received the Ichimura Industrial Contribution Award in 1999.
Features
Superior weather-resistance in environments other than those covered under the JIS standards for weather-resistance.
Two types of nickel-added high-performance weathering steel are available to suit various environments and performance requirements.
- Weather Resistance
- Small-scale exposure testing
Current guidance for application of JIS weathering steel to road bridges in Japan
(Ministry of Construction Public Works Research Institute, Steel Club, Japan Bridge construction Association)
- Airborne salts ≦ 0.05mdd (mg/dm2/day)
- Measurement of airborne salts in the following regions may be omitted.
All other than the chemical constituents are covered by JIS weathering steel.
- As with JIS weathering steel, a range is available for tensile strengths of 40 - 60 kilos.
- As with JIS weathering steel, mechanical properties are guaranteed.
- Steel plate sizes are similar to those for JIS weathering steel.
Comprehensive provision of utilization technology
- We will provide comprehensive utilization technology for fabrication, and we develop high-strength bolts and special nickel-added welding materials for high-performance weathering steel.
Provision of technology for utilization of weathering steel
Applications for weathering steel require greater safety and security in minimum maintenance levels, and technology for a total solution.
- In addition to the conventional windborne salts, the effects of temperature, humidity, and sulfates are considered in forecasting corrosion and wear of steel plate.*
- The amount of corrosion in the first year is measured, and the corrosion environment is quantified using "Wappen test pieces."
- Development to control initial streaming rust along with surface treatments (supplementary additives to stabilize rust)
- Development of surface treatments with consideration for the landscape (colored)
- As diagnostic equipment for management and maintenance, the RST (Rust State Tester) has been developed for rapid and simple measurement of the environmental protection functions of rust films and applied membranes.
* Awarded the 2005 Japan Society of Civil Engineers Tanaka Award (technical papers section)
