Description: ISO-K is a flange system similar to ISO-KF, but designed for larger diameters. The connections are sealed with clamps and elastomer/metal gaskets.

Sizes: ISO-K components are available in larger nominal diameters than ISO-KF, typically starting from DN63 and larger.

Vacuum Range: ISO-K can also be used for rough and fine vacuum applications but is robust enough for applications up to high vacuum levels (10⁻⁸ mbar).

Usage: ISO-K is often used in larger vacuum apparatuses where more stable and larger connections are required.

Steel 1.0037, also known as S235JR or ST37-2, is an unalloyed structural steel with low carbon content, primarily used in construction and mechanical engineering. It is characterized by good weldability, formability, and strength, making it suitable for a wide range of applications such as load-bearing structures, pipelines, and components with low mechanical requirements. 1.0037 is a widely used steel grade due to its cost-effective production and broad availability.

Stainless steel 1.4301, also known as V2A steel or AISI 304, is a widely used stainless steel grade with excellent corrosion resistance properties. It is resistant to moisture, humidity, and mild chemical environments such as water and diluted acids. Additionally, it offers good weldability, high strength, and broad applicability across various industries, including food processing, the chemical industry, and construction.

Stainless steel 1.4404, also known as V4A steel or AISI 316L, is a high-quality stainless steel grade with enhanced corrosion resistance compared to 1.4301. It offers greater resistance to chloride ions and saline solutions, making it particularly suitable for applications in marine environments and the chemical industry. In addition to its excellent corrosion resistance, 1.4404 also provides good weldability, high strength, and broad applicability in demanding environments, including food processing and medical technology.

Stainless steel 1.4571, also known as V4A steel or AISI 316Ti, is a stainless steel grade with added titanium, which enhances its resistance to intergranular corrosion. This steel grade is particularly suitable for applications in environments with elevated temperatures and aggressive media. 1.4571 offers excellent corrosion resistance, high strength, and good weldability, making it ideal for various applications in the chemical industry, petrochemical industry, and food processing.
