Shanxi Jianing Forging provides customized processing of lightweight aluminum alloy forgings and aluminum flanges. The on-site aluminum alloy forging project cases are complete, with products that are lightweight and meet strength standards, compatible with new energy and lightweight equipment.
A metallurgical valve factory in Xiangyang, Hubei, has long been engaged in valve manufacturing under high temperature, high pressure, and corrosive media conditions. To improve product reliability, the plant needed a batch of high-performance alloy steel forgings as key valve body components. After multiple rounds of screening and on-site inspection, Jianing Forging was ultimately chosen as its alloy steel forging supplier.
The original forgings at this valve factory have exposed the following issues during long-term operation:
1. Insufficient material uniformity, causing local deformation of the valve under high temperature and high pressure;
2. Substandard corrosion resistance, premature pitting in sulfur-containing media;
3. Poor consistency in batch supply, with some forgings having micro-cracks inside that affect assembly yield;
4. Long delivery cycles cannot match the rapid production rhythm required by valve manufacturers.
To address these pain points, Jianing Forging offers customized alloy steel forging solutions:
1. Uses vacuum degassing and electroslag remelting processes, which help ensure the purity and uniformity of steel ingots, effectively preventing local segregation;
2. Optimize alloy composition design (such as adding elements like Cr, Mo, V), and enhance the fatigue and corrosion resistance of forgings under high temperatures and corrosive environments;
3. Implements full-process digital temperature-controlled forging + multi-stage normalizing and tempering to eliminate internal stress, achieving a balance between hardness and toughness;
4. Establish a flexible scheduling system to reduce standard parts delivery cycles to within 25 days, support urgent order expediting, and support continuous production for customers.
This batch of alloy steel forgings has passed third-party nondestructive testing and physicochemical testing, and after the customer's valve was assembled, they operated continuously for 12 months without any abnormalities, earning full recognition from on-site engineers.
