JIS G3458 is a Japanese Industrial Standard that specifies the requirements for alloy steel pipes used in high-temperature and high-pressure applications. The STPA series, including STPA12, STPA20, STPA22, STPA23, and STPA24, are chromium-molybdenum alloy steel pipes designed for use in various industries, including power generation, petrochemical, and oil and gas.
The STPA series pipes are made from high-quality chromium-molybdenum alloy steel, which provides excellent mechanical properties and resistance to high temperatures and pressures. These pipes are typically used in applications where strength and durability are critical.

STPA24 | 250 | 400-540 | 20 | 170 |
The STPA series is categorized under chromium-molybdenum alloy steels, which are known for their high strength and toughness. Each grade has specific properties that make it suitable for different applications.
The JIS G3458 STPA series pipes are widely used in:
While the STPA series is widely used, there are alternative grades that may be considered based on specific requirements:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
