1. Introduction and Overview Super 13Cr is a martensitic stainless steel alloy known for its exceptional mechanical strength and moderate corrosion resistance, making it ideal for demanding environments. Originally developed for oil and gas applications, Super 13Cr offers a cost-effective alternative to higher alloyed materials, especially in moderately corrosive environments where chloride-induced stress corrosion cracking (SCC) is a concern. Due to its enhanced mechanical properties and improved corrosion resistance compared to conventional 13Cr stainless steel, Super 13Cr is widely used in industries like oil and gas, chemical processing, pulp and paper, marine and offshore, air pollution control, and power generation. 2. Available Super 13Cr Products and Specifications Super 13Cr is […]

S355J0H vs S355J2H: 中空構造セクションの知識

/カテゴリ: /作成者:

Introduction When working in construction, particularly in infrastructure projects, selecting the right steel grade for structural hollow sections is critical. Two commonly specified grades are S355J0H and S355J2H, both used extensively in structural hollow sections such as Circular Hollow Sections (CHS), Square Hollow Sections (SHS), and Rectangular Hollow Sections (RHS). These grades are defined under EN 10219 (Cold-Formed Welded Structural Hollow Sections of Non-Alloy and Fine Grain Steels) and EN 10210 (Hot-Finished Structural Hollow Sections of Non-Alloy and Fine Grain Steels). This article aims to provide a detailed, expert comparison of S355J0H vs S355J2H, offering guidance on their properties, applications, and suitability for infrastructure construction projects. Understanding S355 Steel Grades […]
