1. High precision: This Malleable Iron Npsl Threaded Lock Nut is made of cast iron material, which has good ductility and is easy to form. It is made using automated processing equipment that ensures all products are dimensionally accurate and meet required specifications with high precision.

2. High strength: This pipe fitting is available in three structures, including heavy, medium and light structures. But they all have high load capacity and a tensile strength of Greater than or equal to 300MPA, which can handle the weight without breaking or deforming.

3. Corrosion resistance: It supports three surface treatment methods, including galvanizing, electro-galvanizing and black oxidation. The former two coat its surface with a zinc layer to protect the cast iron substrate from corrosion, and the latter allows it to react with oxygen to form a black oxide layer to protect the metal from corrosion and enhance its surface hardness.

Pressure: Greater than or equal to 2.0MPA CLASS 150

Maximum Temperature: 200 degree (392 degree F)

Tensile Strength: Greater than or equal to 300MPA

< HB150 (Brinell)

Elongation Rate: Greater than or equal to 6%
