Hastelloy B-3 alloy is a new member of the family of nickel-molybdenum alloys, which has excellent corrosion resistance to hydrochloric acid at any temperature and concentration. At the same time, it also has good corrosion resistance to sulfuric acid, acetic acid, formic acid, phosphoric acid and other non-oxidizing media. Moreover, due to the adjustment of its chemical composition, its thermal stability has been greatly improved compared to the original Hastelloy B-2 alloy. Hastelloy B-3 alloy has high resistance to pitting corrosion, stress corrosion cracking, knife corrosion and corrosion in the heat affected zone of welding.
Hastelloy B-3 alloy is another nickel-based advanced alloy after B-2 alloy. It has a specially designed chemical composition to achieve a higher level of thermal stability than other Hastelloy alloys such as B-2 and has excellent resistance to pitting, crevice corrosion, stress corrosion, knife corrosion and thermal effects ability to corrode. Due to the improved thermal stability of the B-3 alloy, the problems encountered in the manufacture of parts like the B-2 alloy are reduced due to the reduced precipitation of harmful intermediate phases in the B-3 alloy trend. This provides higher ductility than B-2 alloys under thermal cycling conditions such as casting and welding.
This nickel-molybdenum alloy has excellent resistance to all concentrations of hydrochloric acid at ambient to elevated temperatures. It is also resistant to sulfuric, acetic, formic and phosphoric acids and other non-oxidizing media. B-3 also has excellent resistance to pitting and stress corrosion cracking.

| 5. Packing | *All of our nickel alloy seamless pipes and tubes are packaged according to international standards to prevent any possible damage or loss. By default, we will use thick woven plastic bags to bundle the finished pipes together in batches. For some special pipes and tubes that are vulnerable to dirt, scratches, stress, or rough handling, we will suggest using wooden cases for protection. Please note that wooden cases may incur extra costs not only for the case itself but also for increased freight costs, especially when using air transportation. To enhance customer experience, we also provide dedicated packaging according to your specific requirements." |

| Positive Material Identification (PMI) | Guohao Steel can perform PMI testing in house for most stainless steel grades, or we can work with independent labs to complete PMI in order to meet customer specifications. |
| Testing | In some cases, HT/ET/UT testing of the stainless steel pipes may be required. We can assist you with this requirement. |
