Schlumberger SH619188
Schlumberger SH619188 is an internal specification for materials that are corrosion-resistant alloys for tough environments in the oil field, marine environments, and subsea environments. These materials are chosen for their high strength properties, high corrosion resistance, and performance in environments with high concentrations of chlorides and high pressure.
In some environments for oil and gas production, SH619188 may refer to high-performance grades of stainless steel, such as Nitronic 50 or other corrosion-resistant alloys that provide greater strength properties and corrosion resistance than 300-series grades of stainless steel, but also provide toughness and durability properties.
Applications of Schlumberger SH619188
Materials supplied to the SH619188 specification are commonly used in demanding industrial environments such as:
- Oilfield drilling equipment
- Subsea and offshore mechanical systems
- Pump shafts and rotating equipment
- Valves and flow-control components
- Marine hardware exposed to seawater
What is Nitronic 50 ?
Nitronic 50 is a high nitrogen austenitic stainless steel melted as AOD melt type with higher strength and corrosion levels than 316L stainless. This alloy has excellent corrosion resistance and can be cold worked to much higher strengths than standard 300 series austenitics. It is often used in seawater applications such as boat shafts and pump shafts.
