S355JOWP Corten steel is a high-strength weathering structural steel that combines good mechanical properties with atmospheric corrosion resistance. Its alloy composition allows the surface to form a 安定した保護錆層, which reduces maintenance and extends service life.

カテゴリ:

S355JOWP Corten steel is a type of weathering structural steel defined under the European standard for atmospheric corrosion-resistant steels. This material is designed to develop a 保護錆緑青 屋外条件にさらされた場合, which reduces the corrosion rate and increases long-term durability.

Because of its strength and corrosion resistance, S355JOWP is widely used in architectural structures, 橋, and outdoor steel constructions.

Mechanical Properties of S355JOWP Steel

S355JOWP belongs to the group of high-strength low-alloy structural steels. The material provides good mechanical strength while maintaining resistance to atmospheric corrosion.

財産 代表値
降伏強さ ≥ 355 MPa
抗張力 470 – 630 MPa
伸長 ≥ 20 %
耐衝撃性 Suitable for structural applications

The relatively high yield strength makes S355JOWP suitable for load-bearing structural components and large outdoor structures.

Chemical Composition of S355JOWP

The corrosion resistance of weathering steel comes from its alloy composition. Elements such as copper, クロム, and nickel help form a stable oxide layer on the surface.

要素 代表的な内容 (%)
炭素 (C) ≤ 0.16
マンガン (ん) ≤ 1.50
シリコン (そして) ≤ 0.50
リン (P) ≤ 0.035
硫黄 (S) ≤ 0.035
銅 (銅) 0.25 – 0.55
クロム (Cr) 0.40 – 0.80
ニッケル (で) ≤ 0.65

These alloying elements help the steel develop a dense protective patina layer when exposed to weather conditions.

Key Characteristics of S355JOWP Weathering Steel

S355JOWP offers several advantages compared with ordinary structural steel:

  • Good atmospheric corrosion resistance

  • 高い構造強度

  • 屋外環境での長寿命

  • Reduced need for painting or protective coatings

  • 錆びた色合いが特徴的な外観

Once the protective rust layer stabilizes, the corrosion rate becomes significantly lower than that of standard carbon steel.

Common Applications of S355JOWP Steel

Because of its durability and appearance, S355JOWP weathering steel is commonly used in outdoor engineering and architectural projects.
